Personally I reckon we should sign another decent keeper and have them fight it out with Kinsky for the role or, at the very least, keep him on his toes.
Kinsky might grow into a great keeper, and has been v.solid under De Zerbi, but we've got first hand evidence of his performances dropping off a cliff so it could be risky going into next season with him as our number one and some bog-standard number 2 like Austin or an old geezer.
We need someone good enough to step up and our first choice if Kinsky falls apart again. And if we stay up we might be wise to just sign a new outright number 1 like Trafford or similar.
