Toby Alderweireld says he does not know if he will still be a Tottenham player next season, Sky Sports reports.
Manchester United have been linked with the defender, whose Spurs future has been the subject of much speculation for some time.
Alderweireld has a year remaining on his contract and a £26m release clause has led to reports that Spurs could be forced to sell him at the end of the season.
United were linked with him in January and have been tipped to make a move for him in the summer.
“There’s a lot to play for this season. And in the end I have a year contract left at Spurs, so I don’t look further than this season,” Alderweireld said.
“Other things I don’t know. I am very happy at Spurs, so we will see what the future brings.
“I still feel very fit. I think I played a lot of minutes this season so I showed that I am fit – I don’t feel 30, I feel younger.
“So as I said, I am very happy and I just try to watch game-by-game. This season there is a lot to play for so I will give my best for that.”
