Bengaluru, December 3: Tottenham face threat of losing Toby Alderweireld in the summer as the club refuse to break their wage structure.
The 28-year-old is considered to be among the best centre-backs in the Premier League, and could a move away from the North London club in 2018.
According to the English media, Alderweireld, who earns only £50,000-a-week, is seeking much beyond Spurs' £110,000-a-week wage ceiling.
However, chairman Daniel Levy has failed to make a breakthrough in negotiations as the Belgian international pushes for perhaps the last big contract of his career.
His importance in the side has showed in his absence, since picking up a hamstring injury against Real Madrid earlier this month, Tottenham have won just once in five league games.
The Lilywhites have dropped out of the title race, and have subsequently slid down the table into the sixth spot, three points behind rivals Arsenal.
The report also reveals that Mauricio Pochettino's men have the option of extending his contract by a further year, but it would activate a release clause which is really nominal for a player of his caliber.
Should Spurs take up the option of triggering the extension, the former Atletico Madrid star would be allowed to leave for just £25million and it wold be a surprise if no club triggers that low an amount to prise away the Belgian stopper.
The Belgian is believed to be in no rush to put pen to paper on a new deal, despite his side desperate to tie him down with a long term contract.
It is reported that both Chelsea and Manchester City want the Spurs defensive maestro to bolster their backlines.
Spurs must ensure that their extensively tight wage structure does not make their big players unhappy which is the case right now.
Danny Rose publicly spoke about the low wage Spurs give their players and now the Alderweireld should be enough to open Levy’s eyes.
