None will be interesting to sign him for 85 million. Unless Gyokeres's club willing to decrease his release clause. It went from 60m to the 85m, and that's damn crazy!
Not even Arsenal or MU are keen in gambling 85 million for him. He has to find a solution for himself.
In fact, i see no official bid came for him until this time. The worst thing is that he will miss the chances to leave, then keep play for Sporting next season

He's not the one who increased the release clause. Sporting's president did and I think he's pissed off as a result.
Gyokeres is a goal scoring machine that both Arsenal and Man United would like to have in their squad, but his release clause is way too much and I don't think either of them will be willing to pay such an amount for a 27 years old. If the club does not lower their asking price, he will have no choice than to stay in Lisbon next season.
