I think a bit like us at Arsenal a couple of seasons back, there was a nervousness in the crowd that found its way to the players. Man United sensed that I think and took advantage of it. That first half was beyond awful standard wise. Arteta should have made changes at the break to try and address how flat they were. Jesus and Gyokeres were abysmal. Some of the tactical changes Carrick has made were obvious really. Moving Fernandes higher up the pitch is key. Not getting walked through like they were under Amorim.
