However, the Argentine has rejected any suggestion that he will be leaving Spurs for a lucrative move to either the Spanish or Italian giants.
The 45-year-old told reporters: "There is no buy-out clause in my contract, I will stay here next season.
"There are many rumours, but I am committed with the club, no reason to leave the club. I will be here for pre-season."
Spurs were challenging Chelsea for the league title until the Blues beat West Bromwich Albion on Friday night.
