#2 Samuel Eto'o
Samuel Eto'o was one of the most feared strikers of his generation. He won the treble for Barcelona under Guardiola, and another one with Inter Milan under Jose Mourinho. Across the two campaigns, the Cameroonian professional footballer scored a total of 52 goals.
Despite Pep Guardiola winning LaLiga and the Champions League in his first season at Barcelona, Eto'o felt the manager had proved nothing. The former Chelsea man felt slighted about being told what to do.
Eto'o didn't like Pep lecturing him about how a striker should play when Guardiola himself was a midfielder as a player. Both of them reportedly spoke only few times throughout their season together, before Samuel moved to Italy. That was also the only campaign Eto'o crossed 30 league goals.
