Chelsea manager Andre Villas-Boas has insisted it would be wrong to express an opinion about the Carlos Tevez affair without knowing all the facts.
Tevez's actions in the UEFA Champions League game between Bayern Munich and Manchester City on Tuesday have generated plenty of discussion within the football community and amongst supporters.
Roberto Mancini claims he refused to come on as a substitute, allegations denied by Tevez, while the player has been suspended for two weeks as the club investigate.
Villas-Boas refused to be drawn into the controversy when asked for his view on Friday afternoon, preferring to keep his focus on the Blues' Premier League game against Bolton on Sunday.
"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," he explained.
"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."
