#6 Enzo Perez – Valencia – £8.50m decrease
Not many would guess Enzo Perez when asked to name to 10th most expensive Argentine player of all time, but the defensive midfielder’s performances for Benfica in Europe gained him worldwide notoreity and thus, a €25 million fee when Valencia came calling in the summer of 2015.
The tough-tackling midfielder has proceeded to endure a miserable time at Los Che, missing a staggering 31 games through injury, while another 4 through suspensions in just 2 and a half seasons at the club. It’s no wonder then, that Perez has lost 50% of his transfer value, escpecially after turning 30 years old.
There’s not much hope for Perez – while he has been ever present for Valencia this season, racking up 1300 minutes on the pitch in 16 appearances. Given the La Liga side’s poor position in the table due to a poor defensive output, it doesn’t seem like his transfer value will be going up anytime soon.
Jan 2016 value: £17 million
Jan 2017 value: £8.50 million
