In case you're unaware, the widely-respected and annual International Centre for Sports Studies (CIES) Football Observatory list published every January ranks players according to their transfer value, which is calculated by factoring in a player's age, position, contract duration, performance, international status and other criteria while setting it against the current market.
The 2018 list has been published, and sees Cristiano Ronaldo plunge down the rankings. Ronaldo is rated as the 49th-most valuable player in the world, his transfer value put at €80.4 million. Man City's Nicolas Otamendi is two places ahead, valued at €84.8 million, with Anthony Martial one place ahead of Ronaldo. (Value: €82 million).
Neymar is rated as the most valuable, at €213 million, with Leo Messi in second at €202.2 million. Harry Kane is third, and judging by this list, Spurs should only listen to offers starting from €194.7 million.
Dele Alli (6th at €171.3 million), Kevin De Bruyne (7th at €167.8 million), Romelu Lukaku (8th, on €164.8 million) and Paul Pogba (10th on €147.5 million) are the other Premier League players in the Top 10.
Elsewhere, Phillippe Coutinho is valued at €123 million, tens of millions below the fee recently paid by Barcelona. Liverpool shouldn't be too smug, however: Virgil Van Dijk is rated at €50.8 million.
