Harry Redknapp insists that he will continue to take off Rafael van der Vaart when he tires in games.
The Spurs coach also says he will no longer allow van der Vaart to go straight to the dressing room.
The Dutch star has started 20 Premier League games for Spurs, but he has been withdrawn 12 times, and when he does come off he does not hang around to watch the rest of the game.
Redknapp insists nothing will change, apart from the fact Van der Vaart will be told to sit on the bench.
"His fitness is a problem for him. He tires in games at times and you pick up injuries when you're tired," Redknapp said.
"I take him off because I feel he is looking tired and it's my decision at the end of the day what I do. If I decide to sub him, I'll sub him.
"That's why I have played him for 60 minutes or 70 minutes. Can he play 90 minutes on Saturday and then play 90 on Tuesday? I will have to look at him. I don't want to over-do it with him and leave him struggling for Tuesday."
On his tendency to go down the tunnel, he said: "I haven't spoken to him about it but I will do.
"I don't like anyone walking down the tunnel, whether it's him or anyone else.
"I think players should sit on the bench and watch their team play the game together.
"That's how I've always seen it and that's how it want it here."
Redknapp also went into more detail about William Gallas' knee injury, and admits he is really struggling.
"As soon as he went to kick a ball he collapsed in pain so I'm not kidding anyone about him.
"He has had three scans - two this week - because every time he goes to kick a ball, he can't strike it.
"We will shut him down until Monday now. He was out there today but he was way off."
