But Tottenham manager Harry Redknapp has ruled out Robbie Keane making a loan return to any other club.
It is strictly - money up front.
Redknapp: "I wouldn't think that's (loaning out the player) a possibility because we paid good money for him and to loan him out again, it wouldn't be a goer.
"If Robbie's not happy when the season starts and he's not playing then we'll sit down and discuss it.
"And if he wants to move, someone will have to buy him, but I'm hoping he comes back into the team and makes a real impact."
