Yaya has played many games for City while carrying an injury, he didnt look to bad to me at the Villa game so obviously something has changed..
In regards to his agent, he is just doing his job, which is obtain the best financial deal for his client..
I would imagine Yaya pays him a lot of money and so just lets him got on with it..
You have to admit, although his agent is a pain in the ar** he always gets Yaya a fantastic deal..
If i was a footballer, i think i would look at having this guy as my agent.
