Real Sociedad coach Jagoba Arraste is determined to keep hold of midfielder Asier Illarramendi.
"We are not going to pretend that a team that finished fourth and has two players in the Best XI of the Under-21 European Championships is going to have nobody interested in their players. One thing leads to another," Arraste said.
"It is true that we are talking about one of the biggest clubs in the world, both in economic and sporting terms.
"However, we are not going to negotiate for him. He is not for sale. The club has made it clear, and I think the player has too, that we are not going to discuss hypothetical situations."
