The Ayew bashing is ridiculous. It was his cross that gave Kodjia the header.
He just needs to hold his position a little more. Trouble is he wants to be in the middle. He comes inside and that forces RM to have to drop deep or shift to the left. Ayew's got to pick and choose his runs inside a bit more for the benefit of our shape and because he's got the ability to beat a man and cross it.
But he does look most likely to create something today, along with Jack.
I do think too that playing Grealish, RM and Ayew at once is not really working.
