The England international is thought to want more first-team action ahead of this summer's European Championships.
However, Spurs boss Harry Redknapp is refusing to let the 29-year-old leave White Hart Lane.
"[Chairman Daniel Levy] spoke to his agent who said he is not happy because he wants to play and he has got a few clubs in for him," Redknapp said. "I am sure he has got a few clubs in for him but we are not selling him.
"He is saying this club wants him and that club wants him – that is how they make their money. He is not moving anywhere, though. He is on contract here and is a big player for us."
Spurs host Wolverhampton Wanderers in the Premier League on Saturday.
