The Blancos legend has been tipped to make a sensational comeback to the Spanish capital should Lopetegui be removed from his position
Besiktas president Fikret Orman says assistant coach Guti would be allowed to return to Real Madrid were the Spanish giants to approach him to replace Julen Lopetegui.
Although Madrid eased the pressure on Lopetegui with a 2-1 Champions League win at home to Viktoria Plzen on Tuesday, the former Spain coach's future remains in the balance.
Madrid face Barcelona in the first Clasico of the season at Camp Nou on Sunday, a match that could be decisive for Lopetegui's chances of continuing in the role.
