Feel horrible for Rosenior. Bloke was set up to fail from minute one. If you genuinely believe he’s a shit coach cause of this then you do not understand football. He’ll be at the top level again soon.
Sanchez has been the best cross claiming keeper in the world and he makes it look so easy and transitions those moments into threats that people forgot how risky that whole ordeal is (and he saves us with those risks because we lack box dominance on set pieces).
He was always going to have moments in which he slips up. I don't care and you shouldn't either that he made a mistake(s). He should change nothing about how he's been in goal the past year.
