To be honest I'm shocked it's taken this long following his departure to go off and not in the least bit surprised
Looking at it dispassionately, Yaya was a GREAT player for the club and ironically without him and that original group of players Pep wouldn't be here, because we wouldn't have had that early success, in short his contribution to the club can't be overstated.
That being said, personally I never bought the agent is a dick line, if you employ someone to represent you if you are unhappy with what they are doing you fire them, it's that simple. Seeing as Yaya never did that it's clear to me he was acting in what Yaya felt was his best interests.
As for Pep it seems common-sense to me that they wouldn't see eye to eye Pep has shown him the door not once but twice through his career and looking back at his time at the club, I don't think anyone can argue that City got good value for money out of that deal and Yaya could and indeed should have played at the very highest level the vast majority of his time with us.
However, one only needs to watch a Pep team play to see that Yaya isn't a great fit, indeed I would argue if Pep had managed City in 2014 Yaya still wouldn't have been a great fit, that's not because Yaya is African it's because the skills he brings to the table aren't those Pep naturally looks for in his players and finally anyone who has seen Yaya over the last 18 months knows that he has lost a yard of pace and when the ball flows through him it slows the game down, in most teams that wouldn't be an issue, but with City and the way we attack people it's a major problem.
Lastly I want to address the African accusation, is Pep raciest, I have no idea although to be honest I would very much doubt you could be a successful manager or indeed player if you where these days, but for those that think everyone sees all black's as the same and that you couldn't be simply raciest against black Africans(or indeed any subgroup)I have news for you there are people out there that are, I have seen and heard it myself. That being said hand on heart how many of us thought Pep made the wrong choice in not renewing Yaya for another year? I bet there aren't very many of us that do.
