I think he's a decent keeper and nothing more. Look at the goals he let in, got a hand to both Saudi goals (IIRC) and Mbappe's second, yet he let them all in.
Our fanbase is bigging him up to ridiculous levels after winning the WC though. Saying it'll take around 100m to prize him away and that he's undoubtedly world class. Laughable and a little cringe.
