[FONT="]Alderweireld does have a fixed price in his current contract but it does not become active until at least 2019 and not at all unless certain conditions are met.[/FONT][FONT="]The clause actually states that, when Alderweireld’s current deal expires in 2019, Spurs have the option to extend it by a further year – and he would leave for a fee of £25m instead of on a Bosman free transfer should he not sign a new deal.[/FONT]
[FONT="]Tottenham would also have to receive that £25m offer from another club 14 or more days before the end of the summer 2019 transfer window.[/FONT]
