Tottenham are playing the first all England Champions League final since 2008 on June 1. This is despite the fact that the Spurs have spent so little amount on transfers over the last few seasons. Key to the success has been the constant improvement that Pochettino has achieved as a coach over the past few seasons.
Alderweireld first signed for Spurs after his successful loan stint with Southampton came to an end. Now, he has only a year left on his contract. Alderweireld has been a Spurs player since the summer of 2015. His contract has a release clause of £25 million.
If anyone (read Man United) wants to sign him up in the summer, they need to pay the release clause. This clause was activated by Tottenham last December as they risked losing him on a free. The extension added the next season to his contract and a reasonable release clause should he call his time on Spurs.
The 30 year old will still be offered a new deal at the end of the season and should he chose not to extend, then Tottenham will lose him for free. However, if United really want him, they may convince him with higher wages, as his £80,000 a week salary is peanuts at United where benchwarmers earn more than 350k a week.
Alderweireld is critical to the Spurs’ plans, as he played 34 league games and 11 in the Champions League. Replacing an integral part of the defence will neither be easy, nor cheap.
