The Belgian says he will not be signing a new deal any time soon, despite being happy at White Hart Lane.
The Belgian has four years left on his current deal and says he is happy at the club - and that he thinks the club are happy with him.
Nevertheless, the 27-year-old says he will not be extending his current Spurs contract.
“I am not signing. No. We agreed not to," Vertonghen told the London Evening Standard.
"I would prefer not to say why. I still have four years left. I am happy at the club and I think they are happy with me.
"That’s where it ends. I am very happy, we have a good manager, we have a good team and a lot of good players.
"The squad is very big and you have to work hard to play every game and I hope I am playing again soon."
Vertonghen played the full 90 minutes last night as Tottenham came from behind to beat Championship leaders Nottingham Forest in the Capital One Cup.
Next up for Mauricio Pochettino's side are Arsenal in the Premier League, with the first north London derby of the season taking place on Saturday at 5.30pm.
