However, the Ivory Coast international has now moved to dismiss the rumours as hearsay.
"They said I fought with Mario at Swansea and against Sunderland," Toure told the Daily Mail. "That shocked me. My lawyers called me about this and it was the first I knew about it.
"It's just not true. It didn't happen. I am a footballer, not a boxer. People don't know my relationship with Mario. He's not my friend, he's my brother and I love him.
"To say we had a fight is very sad. It upset me and I feel sorry for Mario. He suffers most from these things."
Toure moved to the Etihad Stadium from Barcelona in 2010.
