Arsene Wenger refused to be drawn on the speculation regarding Wayne Rooney's future at Manchester United.
Widespread reports on Monday claimed Rooney will leave United after a breakdown in relations with Sir Alex Ferguson.
It has been suggested contract talks have stalled between both parties and that Rooney could depart when the transfer window reopens in January.
Real Madrid are thought to be at the head of the queue for Rooney should the England star end up quitting United.
Wenger has refused to be drawn on whether he would be interested in signing Rooney, insisting he enough to worry about at Arsenal than concern himself about the player of another club.
"What I make of it is that I have enough problems here not to be involved in that," said Wenger.
"We are not in a transfer period at all.
"We are in front of a big Champions League game and for us it is very important to focus on that.
"Then again, any little incident at Manchester United or Arsenal becomes a big story, but it doesn't mean that there is something real behind the story.
"Maybe yes, maybe no - but I don't know enough to be involved in that."
Wenger, however, maintained even if Rooney were to leave United, it would not necessarily make their title challenge any weaker.
"Chelsea won the championship last year. Rooney was at Manchester United and that didn't stop Chelsea from winning the championship," added Wenger
"What is important is that you perform well.
"What we have learned since the start of the season is that the games we lost, we could have won, and that the team who wins the title will be the most consistent one because everyone will drop points."
