Tottenham boss Harry Redknapp has ruled out Robbie Keane extending his loan at Celtic into next season.

It's understood Celtic's major shareholder Dermot Desmond is considering an approach to Spurs supremo Daniel Levy in a bid to secure another temporary transfer, says the Scottish Sun.

That would be either for the first half of the 2010-11 campaign or for the full season.

But White Hart Lane boss Redknapp said: "I don't see us loaning Robbie out again.

"We paid a lot of money for him. So it's not something I see happening. It would obviously be up the chairman but I couldn't see it being a possibility.

"I certainly would not want it to be happening.

"Robbie's only on loan until the end of this season as far as we're concerned.

"We want him back so in my mind there's NO WAY of another loan deal."
