Barcelona will be hoping that Yamal does not pick up any untimely knocks on Friday when he goes up against a Sevilla side that boasts plenty of no-nonsense defenders. Xavi said: “We treat him like someone who is 16 years old, who is in training. We are very close to him. We see him well when he’s in training. He’ll be up against [Sergio] Ramos or [Jesus] Navas, competitive animals at 36.”
