Too many cooks for me. You've essentially got three number 10's playing. I would take off one of Ayew or McCormack (probably Ross) and bring on Bacuna to give us more width and just get chalk on his boots. That'll allow Grealish to come inside a little more and then Ayew can play where he's itching to, in the middle. If it's still 0-0 after the hour mark I'd look at big Rudy to come on.
Need to inject some urgency in to the game and get the midfield driving at them.
I see the same pattern developing here.
Pundits quite liking ayew at half time . . .
