On Friday morning, the Times broke the story that Spurs appear unwilling to raise their offer of a new contract from £110,000 per week to the £150,000 that Alderweireld is asking for, suggesting the player may well move on in the summer.
"He is an athlete and he could play until he is 40 because his physical condition comes very naturally to him".
"I remember his body language when I watched the game against Liverpool when [Luis] Suarez scored, the season before we came".
'Where are we going if we are letting one of the best centre-halves in the world go?'. Now I think he is a complete centre-back.
"I can't speak for others, every player is different and every player has to look after themselves at the end of the day so I can't say what each person wants".
"Lots of people grew together at the same time so we were all in a great place in our careers and everyone was enjoying themselves and that has carried on now".
"'You are going into a battle, no?' And you cannot show this body language because you are a warrior".
"Physicality is his talent. It is hard after showing this energy to go out and take part in a battle and fight".
Alderweireld has only recently recovered from a serious hamstring injury that kept him on the sidelines for three months and it seems this fresh issue is on the same leg.
Pochettino said he used that game to lift the 30-year-old, who he feels has improved a great deal since then. It would further cement the image of Tottenham as a "nearly club", one happy to cash in on their best players, a team that are so close to success, yet always just miss out. He only needs time to adapt himself to the Premier League.
"I am not involved in negotiation", he said.
Tottenham's resistance to go overboard when dealing with player wages is in many ways commendable.
