"Last summer it was vital that we kept hold of Luka," Redknapp said. "I don't think we will have to do it with people like Gareth Bale this summer.
"Luka, it's different with him. I don't know what he would do.
"I would be lying if I said I was sure that he would stay. You don't know.
"But certainly I wouldn't see Gareth Bale wanting to leave here.
"At the moment he is happy here, a big fish here. He is still learning the game, a young boy, and this is where he needs to be.
"You would like to think Luka would still be here, but you never know."
