FC Porto defender Aly Cissokho has claimed that Tottenham Hotspur have shown interest in acquiring his services but is unsure about his future.

The 21-year old says despite him having another few years to run on his contract at Porto that Spurs are closely looking at him.

"I have a contract until 2012 and the club officials want me to add another year to that," he told Sky Sports.

"That shows they have trust in me and I am proud of that.

"I also know there are big clubs looking at me, Tottenham is one of them and that is fine. I will talk with my club and we will see what happens from there.

"We will just wait until the end of the season and then see."
