Tottenham chairman Daniel Levy is prepared to increase the asking price to £40m for defender Toby Alderweireld when his release clause expires on Friday.
Alderweireld currently has a £25m release clause in his contract, which must be paid in no more than three instalments and within a two year period, but that will end on 26 July, allowing Levy to hold out for more money for the Belgian centre back from any interested parties.
The Telegraph claims that Levy will raise Alderweireld's price tag to £40m following the 26 July deadline.
Despite his low release clause, there has been precious little concrete interest in the 30-year-old Belgian.
