"We've been playing three-game weeks," said the Stoke boss after the 0-0 draw with Aston Villa on Saturday.
"Physically I think we've looked alright, but mentally it's tiring for them and we'll go steady with them."
Pulis also said that he was not worried by Tuncay deciding to head straight for the dressing room after being substituted early in the second half.
"They're from a different generation, so you have to accept that they have different views," added Pulis.
"He gets disappointed every time he gets brought off, but he's been good as gold around the place."
The Potters, who remain 11th in the Premier League, face fourth-placed Tottenham at the Britannia Stadium on Saturday.
