Mancini said: "It's finished. I'm the manager, our focus is on the Premier League and the Champions League. The other things are not my problem.
"The only complication I had two days ago was that we lost against Bayern Munich. Only this. The other thing, no, absolutely."
The 'other thing' was Tevez refusing to come on as a substitute for City at the Allianz Arena - a claim the Argentine denies - while fellow striker Dzeko showed open dissent when Mancini hauled him off.
Tevez has been suspended for two weeks pending a full investigation into the incident by the club.
