#6 Jackson Martinez – Guangzhou Evergrande (Jan 2016: €30 million, Now: €9 million)
Decrease in value: €21 million
Jackson Martinez’s market value has plummeted in the last 18 months, so has his reputation as a lethal goalscorer. Considered as one of the most prolific strikers in world football, the Colombian opted to move to the lucrative Chinese Super League to ply his trade with Guangzhou Evergrande.
His move from Porto to Atletico Madrid in the summer of 2015/16 was hardly successful as the Colombian was struggling for goals in Spain and had managed to net only thrice in 22 appearances. The Vicente Calderon outfit, therefore, decided to ship him to the cash-rish Chinese Super League but that hasn’t resulted in an upturn in fortune for Martinez, who has only netted 4 times since his €42 million move to China.
