The Belgium international still has two years to run on his current deal with Spurs but is yet to agree the contract extension offered to him by last season’s Premier League runners-up.
The reason behind Alderweireld stalling on the new deal is due to the player’s own perception of his market value, and his representative Stijn Francis has warned Tottenham to pay up or risk losing the defender, with numerous suitors ready to pounce on the centre-back’s services.
"When you look at Toby's statistics, they are impressive. Either he deserves an appropriate contract, or else he should be given a transfer," Francis told Independent.
"Seven or eight big European clubs are interested in signing him. There are not many central defenders around who can play like he can.
"But these clubs will have to negotiate with Tottenham's chairman, Daniel Levy."
Alderweireld, whose father also acts as his advisor along with Francis, continued: "I leave everything to my father. We will see what happens in the coming months. But, of course, a great deal has happened recently. I am going to progress still further. I can really see myself getting a whole lot better.
"By adapting my game, I have improved every season."
