Toby Alderweireld has cast fresh doubt on his future at Tottenham.

A target for Manchester United, Alderweireld's contract was extended to 2020 at the turn of the year after Tottenham triggered a clause, but in doing so also activated a £26million release clause in the summer transfer window.

"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," he told Sky Sports.

"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."
