Tottenham boss Mauricio Pochettino has cast doubt on his future with the club.

The manager vowed he will stay at Tottenham 'until the end' — then moments later said he 'can't promise' he will be there next season.

Poch was being quizzed about the possibility of taking over at Manchester United or Real Madrid in the summer.

He said: “I love my job and of course I love a big challenge. When I arrived at Tottenham, I knew very well the challenge would be tough.

“We are victims of our own success, the club was at a different level. I am a very positive person — I am going to stick with the club until the end to help the club achieve all they want."

When asked if this was a good time to promise he would still be at the club next year, given he has been linked with United and Real, the Argentine said: “I can't promise that.

“It depends on the mood of my chairman, on the decision of the company, it's not only my decision.

“I signed for five years. I am respecting my contract. But to sign a five-year contract does not mean you'll be here for ever."
