Manchester City star Robinho has sacked his long time agent Wagner Ribeiro.

Ribeiro, who negotiated Robinho's £160,000-a-week contract at Manchester City, has been told his services are no longer required.

"I am grateful for everything Wagner Ribeiro has done for my career up until now, but our working cycle has come to an end," Robinho said.

"It is time for us to go our own separate ways and I have new goals to achieve with my new club, Manchester City."
