The 10 most valuable U21 players in 2026, explained

Data snapshot: 21 September 2026.

Lamine Yamal is the most valuable U21 player in Oddsivio’s current rankings, with an estimated value of €283m. That is more than second-placed Désiré Doué and third-placed Nico O’Reilly combined.

It is a striking gap. But the more useful story begins when you look beyond the price column: a left-back with a midfielder’s background, a centre-back whose passing stands out more than his tackling, and an €80m attacker still waiting for a substantial weekly role.

This is our cross-league top ten, drawn from 988 eligible players across 16 covered leagues. As in our existing league rankings, “U21” here means aged 21 or younger on the snapshot date. It is not a strictly under-21 list or an international-tournament eligibility list. Every valuation is an Oddsivio model estimate, not a bid, asking price or predicted transfer fee.

How to read the cards: value evolution tracks the estimate over time; squad importance combines recent club involvement and performance. The player profile compares two years of official matches with positional peers of all ages—a 90th-percentile badge means roughly the top 10% for that statistic. Dribbles are attempts. The position breakdown shows recorded lineup roles, rather than personal preferences. Full definitions follow the ranking.

1. Lamine Yamal — Barcelona — €283m

View the full-size Lamine Yamal card.

The difficult part of facing Yamal is not just stopping the dribble. It is stopping the chance that follows.

His two-year profile captures that combination. Among the covered attackers, he is at the 100th percentile for dribble attempts, the 99th for assists and the 97th for key passes—the final pass before a teammate’s shot. His 0.43 assists per 90 are roughly three times the positional average of 0.14.

The reputation has substance beyond our numbers. He finished 2025/26 with 16 league goals and LaLiga’s Player of the Season award, still only 18 when the campaign ended. Barcelona’s award report

His estimate has climbed from €235m to €283m in four weeks. At 84/100, his squad importance is the highest in this top ten: the exceptional estimate comes with a major current role.

2. Désiré Doué — Paris Saint-Germain — €126m

View the full-size Désiré Doué card.

Doué had won two Champions Leagues before turning 21. In the first final, he did rather more than collect a medal: two goals, an assist and Player of the Match in PSG’s 5–0 win over Inter. UEFA’s final assessment, PSG’s player profile

The less celebrated part of his game is worth a look. Across our two-year window, he makes 2.26 tackles per 90, placing him around the 97th percentile among attackers. His key-pass rate is at the 98th percentile. There is work without the ball alongside the chance creation.

His recorded roles are led by right wing, with left-wing minutes too. That breadth makes more sense of the player than a single highlight reel—or a single position label.

The value line also rewards a second glance. Doué is 4.0% below his 24 August estimate, but rose from €120m to €126m in the latest week. “Down over a month” and “up this week” can both be true.

3. Nico O’Reilly — Manchester City — €120m

View the full-size Nico O’Reilly card.

Manchester City’s left-back settled a cup final with two headers. The old midfielder had not forgotten where the penalty area was.

O’Reilly scored both goals in City’s 2–0 League Cup final win over Arsenal, the day after his 21st birthday. City’s account traces those box arrivals back to his midfield upbringing. Manchester City’s match report

Our recorded lineup data tells the story of the transition: 74.5% of his minutes at left-back, compared with 13.7% in central midfield. He is the highest-ranked Premier League player in this list, although his estimate has fallen from €148m to €120m since 24 August.

There is an important wrinkle on his card: the profile still compares him with midfielders, even though left-back is his leading role and the valuation groups him with defenders. His 82nd-percentile goal rate is therefore a midfield comparison, not a claim about where he ranks among full-backs.

His 0.20 goals per 90—about one every five full matches in the two-year sample—fits the midfield instincts behind those Wembley runs. Left-back has become his starting point, not the limit of his attacking contribution.

4. Pau Cubarsí — Barcelona — €105m

View the full-size Pau Cubarsí card.

Cubarsí can break a defensive line without leaving his own.

On his Champions League debut against Napoli, UEFA counted 13 line-breaking passes, more than anyone else in the match. These are passes that find a teammate beyond a line of opponents, removing several players from the defensive picture at once. He was 17. UEFA’s tactical analysis

Now 19, his Oddsivio profile shows 94.6% pass completion, around the top 1% of covered defenders. Completion alone cannot tell us how adventurous those passes are; the UEFA example supplies useful football context for what a passing percentage misses.

His lower tackle and duels-won rates are not a complete grade for his defending; possession and role affect the opportunities to record those actions.

The estimate is up 5.2%, to €105m. Barcelona’s report of his 2026 World Cup Young Player award, after he played every minute for Spain, adds another measure of how much responsibility he already carries. Barcelona’s report

5. Arda Güler — Real Madrid — €101m

View the full-size Arda Güler card.

The goal from his own half gets replayed. The passes between the lines are the part worth watching every week.

Güler’s spectacular finish against Elche in March came with a more revealing explanation afterwards: when playing deeper, he helps build attacks; higher up, he looks to receive between opponents and make the next action count. Real Madrid’s interview

Our two-year profile gives that creative role weight: 3.14 key passes and 0.42 assists per 90, both around the top 1% of covered midfielders. A key pass creates a shot; an assist also needs the teammate to finish. Sitting near the top for both shows how often his passing leads to a shot or a goal.

His key-pass rate is about 2.7 times the midfield average in our sample. His recorded roles span attacking midfield, right wing and central midfield; supplying the next shot is the clear thread across them.

Güler’s €101m estimate is 6.0% lower than four weeks earlier. The creative profile remains strong; the price line should not be used to erase it.

6. Warren Zaïre-Emery — Paris Saint-Germain — €100m

View the full-size Warren Zaïre-Emery card.

One player, two routes into PSG’s team.

Zaïre-Emery’s position breakdown includes 28.4% of recorded minutes at right-back. That is no historical curiosity: PSG’s official lineup placed him there against Marseille on 20 September. PSG’s match record

The midfield profile shows 92.9% pass completion, around the top 1% of that peer group. His shot and goal rates are much less eye-catching. Read together, the numbers describe a player whose contribution is poorly served by a goals-and-assists headline.

His 67/100 squad-importance score places him among PSG’s important players in our current calculation. At 20, he is already being used to solve more than one selection problem.

He had already reached 100 PSG appearances before turning 19. The €100m estimate belongs to a 20-year-old whose flexibility is being used in senior football now. PSG’s birthday feature

7. João Neves — Paris Saint-Germain — €89m

View the full-size João Neves card.

The midfielder who put two overhead kicks into the same hat-trick is hardly short of a party piece. Neves managed that in PSG’s 6–3 win at Toulouse in August 2025. PSG’s match feature

His repeatable work is less theatrical. Over our two-year window he records 2.84 tackles per 90, around the 93rd percentile among midfielders, and completes 92.1% of his passes, around the 99th percentile. Winning the ball and keeping it are a useful combination even on nights without an overhead kick.

His value is almost unchanged over four weeks: +0.2%, still rounding to €89m. His 59/100 importance score sits just below our “Important player” threshold. He nevertheless started PSG’s latest league match, against Marseille: the score summarises a longer spell of use and contribution. PSG’s official lineup

One date to watch: Neves turns 22 on 27 September. He qualifies for this dated ranking; he will age out of a current 21-and-under list then. PSG’s official player profile

8. Estêvão — Chelsea — €80m

View the full-size Estêvão card.

Estêvão introduced himself to Chelsea by scoring against them. His Club World Cup goal for Palmeiras came against the club he was already set to join. Chelsea’s first interview

The longer profile makes the attraction clear. He attempts 6.56 dribbles per 90, around the 99th percentile among attackers, and makes 2.21 key passes per 90, around the 95th. Three-quarters of his recorded lineup minutes are on the right, where a left-footed attacker can carry the ball inside towards shooting and passing opportunities.

The current-role picture is smaller. His squad-importance score is 37/100, “Backup”, and our current-season record contains 153 minutes across six Premier League and League Cup appearances. An €80m estimate is not the same as an established place in the starting XI.

His value is down 7.6% since 24 August. The next step is regular football: enough minutes for that appetite to take defenders on to become a weekly feature of Chelsea’s attack.

9. Kobbie Mainoo — Manchester United — €75m

View the full-size Kobbie Mainoo card.

Old enough to have scored in an FA Cup final; young enough still to make this list. Mainoo is also its fastest riser: +32.6% in four weeks, from €57m to €75m. That is the biggest percentage gain among these ten.

The profile suggests a quieter football story than the value line. He completes 89.3% of his passes, around the 90th percentile among midfielders, and his dribble-attempt rate sits around the 80th. His goal rate is below the positional average. There are ways to contribute from central midfield without becoming a frequent scorer.

Central midfield accounts for 90.5% of his recorded lineup minutes. His squad-importance score of 65/100 places him in the “Important player” tier, while the contract United announced in April runs through June 2031. United’s player profile, Premier League contract announcement

10. Kenan Yıldız — Juventus — €73m

View the full-size Kenan Yıldız card.

Juventus have given Yıldız the No.10 shirt and already made him their youngest captain. The armband arrived against Verona in September 2025; the long-term commitment followed with a contract through 2030. Juventus’s renewal announcement

His position breakdown is almost a split decision: 48.4% of recorded minutes on the left wing, 40.2% at striker. The two-year profile supplies the common thread—carrying and creating—with roughly 93rd-percentile dribble attempts and 94th-percentile key passes among attackers.

There is a significant current caveat. Juventus announced surgery for a broken bone in his left foot on 31 August. The club supplied no return date in that update. Our current-season record contains just one appearance. Juventus’s medical update

Yıldız’s estimate has fallen 23.3%, from €96m to €73m, the largest four-week decline in this top ten. The injury and the movement are both relevant facts; we have not established how much, if any, of that change the injury explains. His longer profile and 66/100 importance score describe a broader period than his immediate availability.

What this ranking tells us

PSG supply three of the ten, but three different kinds of player: Doué combines creation with defensive work, Zaïre-Emery covers midfield and right-back, and Neves pairs tackling with secure passing. That variety runs through the list. A young player’s value can come with very different responsibilities on the pitch.

How this ranking was made

Selection. This is a 21 September 2026 snapshot, during the 2026/27 season. We ranked players aged 21 or younger across Oddsivio’s 16 covered leagues. It is not a retrospective 2025/26 ranking or a census of every professional footballer worldwide.

Values. These are Oddsivio’s weekly statistical estimates, not Transfermarkt figures or transfer fees. Four-week changes compare unrounded values on 24 August and 21 September. Performances, model inputs and season context can affect estimates; the history does not isolate the cause of a movement. How our player-value model works.

Profiles. The charts cover 21 September 2024–21 September 2026, across covered official competitions including internationals. Minutes are weighted equally. Comparisons use broad positional groups, all ages and a minimum of 1,800 covered minutes. Sample sizes vary by metric. Percentiles are not adjusted for competition strength; they describe recorded statistics rather than scouting grades. Passing measures completion; dribbling measures attempts.

Importance and roles. Squad importance combines 70% involvement and 30% performance, using up to 40 eligible competitive club matches in the current spell. Tier names are calculated labels. Positions derive from 730 days of lineup data. A midfield-side label can mean an outside midfielder in a three. Only leading roles appear, so shares need not total 100%.
