According to official sources, Spurs will sign another Juventus player who will be on loan for Kulusevsky for one and a half seasons for a loan fee of 10 million euros and a buyout clause worth 35 million euros.
It is understood that Kulu's loan fee this season is 3 million euros, and next season's loan fee is 7 million euros, for a total of 10 million euros.
Spurs have a €35 million buyout clause that will be enforced if Kulu meets certain conditions (e.g. number of appearances, etc.). And if Koulu doesn't agree on the agreed terms, Spurs can also choose to buy out the Sweden international for the same price of 35 million euros.
In either case, €35 million will be paid in installments of 5 years.
