Toby Alderweireld's agent has urged Tottenham to hand the player an improved deal or allow him to leave the club.
Alderweireld is currently paid £50,000-a-week and has indicated that he would be willing to sign an extension if his salaray was brought in line with Tottenham's top earners.
Both Harry Kane and Hugo Lloris are earning up to double that amount and Alderweireld is seeking similar reward for his impressive displays since arriving in 2015.
Indeed, Tottenham have had the tightest defence in the Premier League in the two seasons since the Belgium international arrived at White Hart Lane.
And while a host of Spurs players have been handed new contracts in the last 18 months, Alderweireld is yet to renew his own deal, which expires in July 2019.
Now Stijn Francis is encouraging the club to make a decision on his client's future.
"Toby is always good," Francis told Belgian newspaper Het Nieuwsblad.
"Even after his injury he recovered well. Tottenham's statistics fell sharply during his absence.

"If you only look at his figures, Toby is impressive and for his performances, he deserves either a correct contract from Tottenham or a transfer.
"For a transfer, you know that he can only leave Tottenham for seven or eight teams and almost all the other top clubs are interested in Toby.
"There are not a lot of central defenders of his kind so they are sought after. But those clubs also know that they have to negotiate with [Tottenham chairman] Daniel Levy."
