Let me start by saying that racism has no place in any civilised society and if something ever does come out to give these claims any credence then I will be the first to apologise but this is my take on it.
If there was any suggestion of racism then Yaya should have gone public while still at the club, he should have refused to play for the club on a point of principle until action was taken against Pep. He should have refused to be part of any presentation involving Pep at the end of his final game with us. The fact that none of this happened leads me to believe that Yaya is just a very bitter man who can not get past his own ego. Did he really think that he was going to have a leading role in a Pep team with a high press. For the last two or three seasons 95% of all the fans were claiming that he was in decline and the Yaya of old long gone.
Was he racist to Zabba, Clichy, Kolarov, Hart, Willy etc.. when they were deemed not suitable for what Pep was trying to implement? Was he being racist to Aguero when he dropped him as he didn't feel he was working hard enough? No
I will always remember Yaya as a great player but outside of this he can go fuck himself.
