Keeper didn't really have control of it, but looked like he was about to when Azpilcueta nudged it out of his hands.
Borderline, I reckon the goal should have stood but can't complain that it was disallowed as he did nudge him in advance. And yes, he should have been sent off earlier.
I'd fancy Arsenal against either of these tbh. Teams look out on their feet perhaps but also look like they've had their season and are ready to go on holiday.
