It all started in 2004 when Chelsea signed Mateja Kežman who just had a stellar season at PSV Eindhoven among other stellar ones. He had scored 38 goals in 40 games for the Dutch outfit alongside Arjen Robben, the pair were hailed as ‘Batman and Robben’ in the Dutch Eredivisie. But a £5.3m move to Chelsea changed dynamics of things.
Kežman, once a goal machine in Holland, scored just 4 goals in 25 league games and 7 goals overall in a total of 40 appearances. Chelsea won the league that season but despite that, the quality in attack was too much for Kežman’s misfortunes to affect the season. Kežman left for Atlético Madrid the next season for the same fee he was bought by Chelsea from PSV.
