Louis van Gaal admits butting heads with some of the game's biggest names.
The Holland coach and Manchester United manager-in-waiting is tipped to take no prisoners when he takes charge at the Old Trafford giants after the World Cup finals.
But speaking ahead of Wednesday's friendly against Wales here, Van Gaal said it remains important for him to be liked by his stars.
He said: "Yes. I think it is very important. I am a coach who wants a good relationship with my players.
"I do everything to reach that level but sometimes it is not reachable as the players are not open-minded and don't adapt to the norms that I put in the team.
"Most of the players say lovely things about me. There are also players who are very angry with me - Franck Ribery, Luca Toni, Hristo Stoichkov and Rivaldo."
