Going forward good, but defensively suspect. He particularly struggled once they changed their shape. Its a worry that both him and Moreno look better going forward than they do defending the goal.
I do remember criticising Ramsey for the same thing a few years ago and he's vastly improved that aspect of his game. I'm sure Emery will be all over it but for now I'd much prefer to see him in play as a striker or in the Tielemans role to negate any defensive frailties.
