I can say from what I've seen, which isn't much. But what I have seen hasn't been much if any better than what we have. They're asking £70m which for me for him is way too much.
He conceded one goal which was not a mistake, he didn't make mistakes from what I have seen, so why according to you he is not much better than what we have? What we have regularly make mistakes.
I have seen him in more than just two World Cup games. There is more football played than that you know.
I've seen a few Roma games through the season as well as our ECL games. He looks like he's no better on crosses and looked equally shakey as both Migs and Karius in one game even though he didn't concede.
So, based on a few games, more than just the World Cup, he's not much better than we have and especially not worth £70m.
