"Man City" captain Yaya Toure could leave © EuroFootball.com

"Manchester City" club can already lose one of the team leaders Yaya Toure this summer.

The footballer's agent hinted that the club is behaving improperly with the Ivory Coast national team member and this summer the defender could leave Manchester.

"Yaya is disappointed, so he is thinking about leaving. There were a few incidents that really upset him. Now he needs to focus all his attention on the World Cup," said the footballer's agent Dimitry Seluk.

"However, 'City' has treated him disrespectfully, so he feels offended."

Y. Toure signed a new long-term contract with the club last year, but the footballer's agent says that money is not the issue.

"They don't realize that good relationships cannot be bought. It's not about money or contract. They have shown disrespect to the footballer. I will repeat, it's not about money. To tell the truth, he would agree to return to 'Barcelona' for significantly less money," said the agent.

Y. Toure has been playing at Man City since 2010. The footballer moved to Manchester from the Barcelona club.
