Lamine Yamal has been valued at a staggering £309.4 million — more than double the price tag of Kylian Mbappe — as Football Observatory’s latest statistical model reveals the world’s most expensive footballers ahead of what promises to be a busy summer transfer window.
The 18-year-old Barcelona and Spain winger, already a World Cup winner and Ballon d’Or contender, tops the global rankings by a considerable distance, with Manchester City’s Erling Haaland second at £196.4 million. Mbappe, despite leading Real Madrid and preparing to spearhead France’s World Cup bid, is valued at just £143.2 million — a figure that reflects a difficult first season at the Bernabeu and the realities of his age and remaining contract length.
Perhaps more striking is who sits fourth and fifth. Michael Olise of Bayern Munich is valued at £121.2 million, with reports suggesting Real Madrid are preparing a bid, while Aston Villa’s Morgan Rogers comes in at £118.2 million — higher than both Jude Bellingham (£103.9 million) and Florian Wirtz (£107.2 million). Rogers, who is hoping to star for England at the World Cup, has been linked to Arsenal and Chelsea in recent months, and his valuation will raise eyebrows among those who assumed Bellingham remained England’s premium asset in the transfer market.
The Football Observatory list, which uses a statistical model assessing age, contract length and ability, also highlights two Premier League sides punching above their weight in the valuations. Bournemouth appear twice — their Brazilian forward Rayan, who joined in January as Antoine Semeyo’s replacement, is valued at £86.7 million, while 19-year-old Junior Kroupi, attracting interest from Arsenal and Chelsea, is worth £76.9 million under contract until 2030.
Among the other notable figures, Bukayo Saka is valued at £96.1 million and Cole Palmer at £95.6 million, while Desire Doue comes in at £115.1 million and emerging Manchester City talent Nico O’Reilly is placed at £108 million. PSG’s Champions League final hero Khvicha Kvaratskhelia is valued at £87.2 million.
Perhaps the most sobering number on the list belongs to Declan Rice. The Arsenal midfielder, bought for £105 million in 2023 and now central to both club and country, is valued at just £65.7 million — a theoretical loss of nearly £40 million on his purchase price. Manchester United’s Benjamin Sesko comes in at £72.5 million, marginally below the £73.7 million United paid for him last summer, while Rasmus Hojlund — who completed a permanent £38 million move to Napoli this week — is listed at £87 million, close to what United initially spent on him.
Andy Robertson’s free transfer to Tottenham from Liverpool, confirmed on Friday, meanwhile serves as a timely reminder that not every move this summer will involve nine-figure fees.
