Yaya Toure has backed up claims made by his agent that he is unhappy because Manchester City didn't celebrate his birthday appropriately.
The Ivorian scored 20 goals last season to help City win the Premier League, and will star for his country at the World Cup next month.
However all is not well at Manchester City, who demonstrated 'they don't care for him' after failing to make a bigger deal of Toure's 31st birthday according to his agent - which could prompt his exit from the Etihad Stadium.
"None of them shook his hand on his birthday. It's really sick," Dimitri Seluk told BBC Sport.
"I hear one newspaper has written that Manchester City congratulated him from Twitter but this is a joke. It is better they don't put anything on Twitter if they are not saying anything to him.
"The club's owners ate a 100kg cake after winning the Premier League this season but when they and the players were all together, none of them shook his hand on his birthday. It shows they don't care about him.
"Of course Yaya is upset about this. If this happened to you as a journalist in the BBC and nobody shakes your hand, you will say bye-bye and go to work for somebody else. It is normal."
Toure took to Twitter this morning to defuse the row following Seluk's comments by insisting that his performances on the pitch showed that he was committed to Manchester City, before adding that only fans should only believe what he says, rather than his agent.
However an hour later the former Barcelona man returned to the social networking site to explain his stance once more, and back up what his agent had said.
He wrote: "My agent was trying to make a point here on my behalf, joke aside. It seems important for me to make a statement..i am going to do so."
"Everything Dimitry said is true. He speaks for me. I will give an interview after world cup to explain."
Toure has been a key player for Manchester City since joining from Barcelona in 2010, helping the club win the FA Cup as well as two Premier League titles.
As yet Manchester City are yet to make a comment.
