In my retired keepers opinion, he is a perfect number 2 who can pull out worldies but is too inconsistent to be a number 1 even for sides down the table.
He is a very good at reflex saves and is slightly above average with his feet but his movement around the goal is poor thus conceding goals that either he probably should save or makes it’s look like he has conceded a worldie plus his command of the box is below average.
Given the resources and pull that city have I’d be extremely disappointed if I was a fan of them with this signing.
