Arsenal manager Arsene Wenger believes dressing room comments should remain private after Roy Hodgson was criticised for telling a monkey joke.
Hodgson has had to issue a public apology over his half-time comments - despite Tottenham winger Andros Townsend and Manchester United striker Wayne Rooney defending the England manager's remarks.
The incident has taken some of the shine off of England's impressive 2-0 win against Poland and their subsequent qualification to the 2014 World Cup.
Wenger has since admitted he does not know why a player would want to leak a team talk.
The 63-year-old, speaking ahead of Arsenal's match against Norwich City, said: "You basically want (everything) to remain in the dressing room - it is an old phrase which you know well in England.
"But unfortunately these times have gone, so today you have to be very careful about what you say, wherever you are.
"I must say that I don't really know what happened, but we can go sometimes a bit overboard at half-time, it is an emotional situation, there is a lot of desire and effort in there.
"I don't really know what happened. What has he really said? What does it really mean? You have to be in the situation to know - I don't know really what happened.
"You have to adapt to the culture of your team. When you go to Japan, you have to be cautious, because what looks normal in an English dressing room, suddenly looks completely shocking in a Japanese dressing room.
"You adapt to the culture of where you are, but sometimes you can say one word stronger and that is not politically correct, that can happen to any manager."
Wenger also revealed at his pre-match press conference that he had been offered a new two-year deal but refused to be drawn on whether he was going to accept the contract.
