I've just looked at a few numbers (mainly saves per goal) and Pickfords ratio is very ordinary. Forget the mistakes (which can happen to young goalkeepers) but he has gone backwards since Sunderland. At Sunderland he made 2.7 saves per goal conceded. At us that has been 2.08 and then 2.03 saves per goal.
To give some wider perspective Stekelenberg is 1.79, Emerson 2.35, De Gea (having a torrid season) is 2.51 (and was 4.1 last season) Fabianski is 2.52 & Kepa is 2.47. Only Stekelenberg seems to be worse than him (Mignolet last season was 1.5).
Either way, we took a chance on a lad who in a chaotic football club, as a young goalkeeper made a commendable 2.7 saves per goal. As he got older you would hope this would move upwards, potentially towards the 3 mark. If he'd have just matched his Sunderland output we'd have conceded 25 goals this season.How many points would that have been worth 6/7/8?
If he'd have matched Alisson we'd have conceded 18 goals this season so far. I dread to think where we would be in the league. What you get is Alisson is a truly World Class keeper and Pickford is some way off.
It's not just the mistakes he's making either. His all round bread and butter game is very ordinary and has actually significantly regressed.
