The Frenchman enjoyed a breakout season with Spurs after initially struggling to find his feet in north London.
Speaking on Canal Football Club, the 29-year-old said: "Today I feel good over there (in London). This year everything is going well for me.
"I am still under contract with them so all is good. But you know it better than me, anything can happen in football very quickly.
Asked if his career plans were linked to manager Mauricio Pochettino's future, Sissoko added: "Not necessarily, I don't know.
"At the end of the season, it could be that they have a new project, that a new coach comes, and he doesn't count on me, he wants to sell me.
"Many different things could happen. But for the moment I feel good there, I am happy there, and in my head I have no thoughts of leaving."
