My goalie knowledge is bang average but isn't it a bit sly to compare him to the two mega keepers of the last 5 years?
What age do keepers who aren't prodigies start holding their own as a #1?
Yeah as @Lxxx
mentioned my point was more that keepers don't normally start becoming a number 1 and developing at near 27 you get a lot of keepers these days who play from a lot younger. And also a hint of if we are going to challenge at that level then we are going to need a keeper who is of a lot higher level than Robles.
But while we are at it I've looked at some of the keepers who'd I'd say are at Europa level rather than top level....
Forster by 27 - played about 250 games for Celtic and Southampton between 22-27
Mignolet by 27 - played about 200 games for Sunderland and Liverpool between 22-27
Begovic by 27 - played about 200 games for Pompey and Stoke in the PL between 21-27
Szczesny by 26 - Same age as Robles and he has played 250 games for arsenal and Roma
David Ospina by 27 - played over 200 games for Nice and arsenal
Vorm by 27 - played over 150 games in the Eredivisie by that age
Karius by 23 - Has played about 25 games more at the top level so far than Robles and is 3 years younger than him
Can look more around Europe and see people like timo horn who is 23 and played over 150 games for the Koln first team. Leno who is 25 and played almost 300 games for the Leverkusen first team.
I guess my point is if Martinez had thought Joel had it in him to become top class he wouldn't have stuck with Howard until right at the end. And if koeman thought he had it in him to be good enough he wouldn't have used Stekelenburg until he got injured. And that I just don't see Joel suddenly jumping to the levels needed to be the keeper we need moving forward given where we want to go are even are at now.
