PSG coach Laurent Blanc is wary of being caught up in mind games with Chelsea rival Jose Mourinho ahead of their Champions League tie.
Blanc dismissed Mourinho's comments as nothing more than mental sparring, and claimed he has no interest in retaliating.
The Frenchman said: "Did Mourinho win the psychological battle [last season]?
"If he wins a point, it is because he's playing a game. I have no game to play mind games with Jose.
"We know him, we know him very well. [The media] like that, you like his quotes, that's it.
"He's very strong in this aspect but not only that."
