Tottenham expect to strike a new deal with Toby Alderweireld long before his £25million release clause can be activated.
Details of Alderweireld's current contract, worth £50,000-a-week plus appearance bonuses, were revealed by the website Football Leaks on Monday, and expanded upon on Tuesday by Belgian newspaper Le Soir.
These included a clause which seemed to offer rivals the chance to buy the Belgium international centre half in his peak years at an attractive price.
However, the clause cannot be triggered until the summer of 2019 when the contract is due to end, by which time Alderweireld will be 30.
