Being optimistic, I think we could benefit from the absence of home fans. We've all heard the crowd getting restless at some of the slow build-up and the players won't be under any pressure to launch it instead of following the plan. And there won't be the mass exodus to the trains five minutes from time. Away from home we've done okay in recent (!) games, plus we're due a win or two. Ally Mac will be an unknown quantity for opponents and will unlock defences enough times that even our forwards might score.
Being pessimistic, ... no, let's not.
I sort of agree with this. Plenty of the players look pretty uncomfortable in home games. Partly maybe because of that restlessness you mention but mostly I think its a squad personality thing. A lot of the players seem humbled just to be in the Premier League, like its a big fat privilege they are carrying around in a heavy backpack on the field. In away games some of that pressure seems to be off and I could imagine playing in empty arenas could help as well.
I think the signings of the summer, like Maupay, Mooy and even the so far unfortunately shit Trossard is a step in the right direction. They are not just happy to be in the Premier League, they demand to win and believe in their own ability in a different way than many of the other players in the squad. A few more players with that mentality and things would look better.
