​Tottenham Hotspur defender Toby Alderweireld has reportedly informed the club of his decision to forego the signing of a new contract.

According to Italian football expert ​Gianluca Di Marzio, the player, who has a £23.4m release clause in his current deal, doesn't intend to pledge his future to the London side.

Last month, the Daily Mail reported that Tottenham were close to securing Alderweireld to a five-year deal which would also remove the clause. It would also see him earn £75,000 every week.

However, it appears that they have been unsuccessful in their attempts to convince the player to follow in the footsteps of teammates Harry Kane, Dele Alli ad Hugo Lloris, who have all signed fresh deals.

Mauricio Pochettino will be quite disappointed by this development if it is indeed true. The Argentinian manager views Alderweireld as a key part of the club's future, and the fact that he isn't willing to commit will definitely be worrying.

Alderweireld thinks very highly of his manager as well, recently stating that Pochettino was up there with the very best he'd worked under.

“The manager is very important. He has an idea how he wants us to play," He said.

“Sometimes it’s a good result and sometimes a bad result — but he stands by his philosophy. He doesn’t want to change and it’s the way we want to get success, with good football and pressure.

"And it’s good to have a manager who is very clear. He’s up there with the best I’ve played for.

"But I’ve been very lucky to have been under some of the world’s best managers. Diego Simeone, Frank de Boer, Marco van Basten, fantastic names.

"Mauricio gets across his ideas to the group and we know exactly what he wants.

"Now I think he is one of the best in the world."
