As Deulofeu showed he is slow to react to react on early shot. Plus his distribution isn't ederson amazing. 7/10 seems fair considering the money paid for him
That was hit very well, low, hard and with little backlift. There are some shots you just don't save.
It is all about the probability game for the keepers. Allison's positioning is probably his greatest strength, keepers use that to close down the angles and make it hard for the opponent to score. But there are still a few spots that if the striker of the ball managed to find it, leaves the keeper with no chance regardless.
Allison has saved a huge amount of shots taken at close range, sometimes making them look almost effortless because of his top class movement and positioning work. Ming and Karius are good shot stoppers, but on close range you always fancy the striker. That's why they are merely decent, while Allison is almost world class.
He is a huge upgrade for us.
