4. Roque Santa Cruz
Having been in mediocre form for almost a decade and known for his injuries as much as for his blazing 19 league goals in just 37 matches for England, Roque Santa Cruz has had a tumultuous journey. His stellar 19 goal performance led Mark Hughes’s side to be no.7 in the league, and the player was often highly bid for earlier. However, this footballer from Paraguay performed poorly for Manchester City, who hired him for a staggering 17.5 million, scoring only 3 goals in 4 long years, which works out to be roughly 6 million per goal!!
