Former Real Madrid sports chief Pedja Mijatovic admits he's a big fan of Real Sociedad striker Alexander Isak.

Isak has played a huge role in La Real's successful season so far.

Mijatovic told SportExpressen: "He is a player with great qualities. He is very calm, hard working and very professional. I understand that people are happy with him.

"He has had a fantastic season. It is a pity about this interruption because he had found good form. He is a boy who will become a great football player. I have no doubt at all. He has everything to be a big striker in Europe. It depends on many circumstances such as injuries. I don't know if he will be the best or top three, but he has a great future.

"The big teams in Europe are looking for the best attacking options and Isak is one of them. So it's normal for many teams to follow him."
