#1 Samuel Eto'o
The 37-year old is currently playing for Qatar SC as a striker, and is considered one of the greatest African footballers of all time, having an unbelievable goal scoring record for Barcelona and the Cameroonian national team. His goal in the 2009 UEFA Champions League finals was an extremely important one, as Barcelona went on to win the title against Manchester United.
A lesser known fact about the Cameroon international is that he was a product of the Real Madrid youth system, and graduated successfully to the senior team in 1997. He is one of the few players who have played for both Barcelona and Real Madrid.
With only 7 appearances in 3 seasons, Eto'o was sent on a loan spell to various Spanish clubs, until his permanent spell at Mallorca. Unsurprisingly though, Eto'o's transfer is something that Los Blancos have found to be 'regretful', as his success with rivals Barcelona was quite obvious.
