However, activating that option will activate another clause which will allow the defender to leave the club for just 25 million pounds next summer.
The injury will hardly help the Belgian international's cause as he presses Spurs to increase their offer of a new deal which now stands at £110,000-per-week - £40,000 per week below what Alderweireld thinks he is worth. "He was slouched in the tunnel", Pochettino continued.
"When I came, I told him: 'Why are you like that?" We have worked a lot together to reach the level that he is at today.
The Tottenham Hotspur centre-back is widely considered to be one of the best in the world.
'He's an athlete. It's unbelievable and it's only up to him to play until he is 40-year-old because his condition is genetic. "You are going into a battle, no?'" he said.
"He has unbelievably quality, physical condition, technique", Pochettino added.
"You can not show this body language because you are a warrior".
They are one point behind fourth-placed Chelsea and four behind second-placed Manchester United who play each other on Sunday, so victory in south London would be a huge boost.

That seemed to contradict North Korea's own claim that it had no interest in meeting with Pence while he was in Pyeongchang . Kim now heads the United Front Department, the North's office responsible for inter-Korean affairs.
Pochettino said he used that game to lift the 30-year-old, who he feels has improved a great deal since then.
The question, of course, is whether Spurs could keep Vertonghen for that long, given the difficulty they are experiencing in extending Alderweireld's deal.
"The club believe that he needs to be rewarded".
"We need to think of [reserve centre-back] Juan Foyth too".
"I'm not involved in the negotiations and I don't want to be because that job is so hard".
It would be a massive blow for Mauricio Pochettino given how integral the player has been to the success of his Spurs side, but is he really indispensible?
