France star Kylian Mbappe tops the rankings in a new list of estimated transfer values released by a respected international football research group.

The 2018 FIFA World Cup winner heads the list for Europe's 'big five' leagues produced by the International Centre for Sports Studies (CIES) Football Observatory. 

But the next six places are occupied by either English or Premier League players.

Liverpool have Mohamed Salah and Sadio Mane in that group and also possess the highest-ranked player in every defensive position, while Leicester midfielder and reported Manchester United target James Maddison also features prominently.

After Mbappe, rated by the CIES at a value of €265.2 million, which would break the world record held by his Paris St Germain team-mate Neymar, England have four players valued higher in the study than Barcelona star Lionel Messi.

The CIES model draws on a player's performance for his club and national team, his age and position, as well as the league he plays in and the "economic level" of both his club and those potentially wishing to sign him.

The Premier League's financial strength therefore adds to the estimated value of its players while Messi's age, 32, counts against him.

Manchester City forward Raheem Sterling is the only player other than Mbappe rated above €200 million at €223.7 million, with a drop-off to third-placed Salah at €175.1 million.

He and Mane sandwich Borussia Dortmund's fourth-ranked England international Jadon Sancho (€168.9 million), with Tottenham and Manchester United's respective England strikers Harry Kane and Marcus Rashford also ranked ahead of eighth-placed Messi.

The Argentina forward's €125.5 million estimate and club-mate Antoine Griezmann at €123.6 million make them the last two £100 million players in the list.

Maddison ranks 12th at €112.4 million, the highest-ranked midfielder in a list dominated by attackers, while 20 players break the nine-figure barrier in euros, the last being Inter Milan's Romelu Lukaku at €100.2 million.

Premier League front-runners Liverpool have not reproduced their clean-sheet record from last season but the CIES study still thinks highly of their defence.

Trent Alexander-Arnold is the highest-valued full-back at €110.5 million, which ranks him 15th overall and sees him join Maddison as the only non-forwards over €100 million.

Virgil Van Dijk is the top-rated centre-back, 29th overall at €92.7 million, while Alisson Becker is five places back as the number one goalkeeper at €87.6 million.

Forward Roberto Firmino is ranked 14th overall, one place and €1 million ahead of Alexander-Arnold. Just behind the young full-back is Richarlison at €104 million, providing some solace for rivals Everton.

Age is a significant factor in the rankings. The top 20 players have an average age of just over 24, with Messi the only player over 30 in that section.

Messi's long-time rival Cristiano Ronaldo, now 34, ranks 49th at €80.3 million.
