Atleast Sanchez has pace, so if he can cut out the errors, he can turn into a quality CB. Look at how Richarlison wrecked Ald a few days ago, very worrying.
Richarlison running wide into the gaping void filled by Mou's stupid insistence on always (predictably) playing an overly attacking RB exposed us not just for Toby's age/decline and lack of pace, but also Mou's lack of anticipation and imagination with his tactics. It was a really poor display all around.
