He’s a good keeper, not ‘world class’ or ‘top quality’ just a good keeper.
A good keeper who has the potential to be a top quality one, imo.
He's just 24.
Alisson was an unheard of sub until this time last year.
Does he not have the potential to be a top goalkeeper either?
Every - every single one - goalkeeper makes errors. When they do, they result in a goal, more often than not. Making mistakes goes with the territory. It's how the keepers react and respond when they do happen which goes towards making them a top goalkeeper.
