"I don't think Berbatov's head is there anymore," he said. "It is not with Spurs and I think he is looking for a move.
"I think he is a very important player for the club. You can see Spurs without Berbatov are a different team. Without Keane as well they are a different team.
"They are huge players. It will be very difficult to replace Berbatov. He is a class player. He is not affected by anything around him. It was the same with Keano. He is one of the best players I have ever played with. Losing them I think will be difficult for Spurs."
