Jose Mourinho is keen to have more resilience at the back to make a serious challenge for the Premier League title, despite having Eric Bailly, Marcos Rojo, Phil Jones, Victor Lindelof and Chris Smalling in his arsenal.
But Pochettino is pleased to have retained the services of a group who have finished third, second and third, over the last three Premier League seasons.
"I'm not confident, I'm not confident as the market closes today so it is time at least for me to stop thinking about the market because the market will be closed".
However, we can compare Alderweireld's 16/17 season where the Belgium global played 30 matches for Mauricio Pochettino's side.
"The club made a massive effort to try and extend contracts of Harry Kane, just one example".
"The club is doing an awesome effort to try to finish the stadium as soon as possible, and the lodge finished at the training ground".
"It is hard to understand for people in football that Tottenham didn't sign or didn't sell players - but sometimes in football, you need to behave different". If we can not improve our squad it's better to keep our squad all together.
"We have a lot of players". But in four hours it will be hard to sign some players.
"Of course it's hard to understand for people that Tottenham didn't sign or sell players, but sometimes in football you need to behave differently".
"I can understand there is some speculation because we have good players and they are interesting for some other teams".
Mourinho asked a question about his own future when he offered up Martial as one of the big-names United should sell this summer and if the striker is still in his squad when the transfer window shuts at 5pm tomorrow, he will have his answer.
Pochettino had been linked with several players and a fresh approach for Aston Villa midfielder Jack Grealish was rebuffed by the Championship club earlier this week.
"I am not anxious, I am not sad, I am so happy".
