The KPMG Football Benchmark - an interactive platform which analyses the operational, financial and digital performance of football clubs and players - have put together a list of the top five players in Europe by both increase and decrease of market value.
Bayern Munich sensation Alphonso Davies has seen the biggest increase in the continent, with the 19-year-old’s now estimated to be worth £73million - which represents a £35million jump.
Davies played an integral part in Bayern’s Champions League triumph last season, producing a number of solid performances in wins over Chelsea, Barcelona, Lyon and Paris St-Germain.
Next in the list comes Arsenal’s Saka, whose increase of £26million now gives him an estimated market value of £43million.
The 18-year-old became an important member of Mikel Arteta’s Gunners squad last term, registering 11 assists in 39 appearances.
Fernandes finds himself in third place with an increase of £23million, giving him a total value of £88million, having single-handedly transformed United’s fortunes after completing a £67million switch from Sporting Lisbon in January.
The Portuguese midfielder comes before Manchester City’s Phil Foden (£19million increase to £47million) and Napoli’s Victor Osimhen (£19million increase to £53million).
Then comes the five players whose market values have plummeted this summer - and top of the list is Coutinho, whose decrease of £14million means he is now believed to be worth £56million.
The Brazilian failed to land himself a permanent move to Bayern after spending the 2019/20 campaign on loan in Munich, but Barca remain desperate to get him off their books before the summer window closes.
