Tottenham are expected to trigger their option to sign Dejan Kulusevski at the first opportunity this summer.
Spurs have two windows in which to buy the Sweden winger following the 18-month, £8million loan deal they struck to sign him from Juventus in January.
They have an option to sign the 21-year-old permanently for £25m at the end of this season.
That option would remain in place for another 12 months, but Spurs would be obliged to sign him for £30m if he plays in at least 50 per cent of Spurs’ Premier League games for a minimum of 45 minutes next season and they qualify for the Champions League.
