Chelsea boss Andre Villas-Boas admits he's never had to deal with a situation like Carlos Tevez's row at Manchester City.
Tevez is currently serving a two-week suspension for disobeying manager Roberto Mancini's instructions during Tuesday night's Champions League game at Bayern Munich.
Villas-Boas refused to be drawn on the controversy, saying: "When it's not my business and I'm not in full control of the information, I cannot emit an opinion because that opinion might be false.
"It's nothing to do with me. It's up to Man City to deal with the situation.
"Everybody has to deal with their own problems."
Villas-Boas was also reluctant to provide details on how Chelsea would deal with a similar alleged revolt.
Revealing he had never been put in that position, the former Porto boss said: "If that happens, we will have to look at the situation and we will have to set up a pattern of coherence in the actions that we do."
