"He refused to go in. He refused to come on the pitch," a visibly frustrated Mancini told Sky Sports News after the match, which ultimately ended as a 2-0 defeat for the Premier League side. "For me, it's a bad situation because in a game like this it's impossible for one player to refuse to come on, but also for the team because he didn't play."
Speaking to written media later, Mancini said Tevez was "finished" at the Etihad, adding: "If I had my way he would be out of the club."
The 27-year-old striker reportedly explained his actions by saying that he did "not feel good mentally".
Tevez was subject of much controversy over the summer, repeatedly insisting that he wanted to leave the club and return home to Argentina.
