Aleksandar Kolarov has cast doubt on his future at Manchester City.

The Serb admits he was frustrated last season as he battled fellow left-back Gael Clichy for a start under former City boss Roberto Mancini.

"I'm in constant contact with my agent and soon we will know what may happen," Kolarov told

"At City I'm happy, but I want to be playing regularly as I said to former coach Roberto Mancini. Money is not everything in life and I have no problem to revise my salary. The only thing I want is a team that allows me to play as a starter."
