I'd be okay with him as our #1 next season.
I hope you're not serious. Pinto from 2 seasons ago maybe, but not at his current form/age. He would do well in La Liga, but what about Champions League?
37 is still relatively playable for goal keeping. All you are required to do now and then is jump and dive. Edwin Van Der Sar did it till his 40's if memory serves.
99% of keepers only need that ability, but as a Barca keeper you need to be a sweeper... and that requires a special set of skills that many keepers would take large steps to avoid
Barca keeper being a sweeper...meh! It just requires a starting position nearer the 18-yard line.
Looking at a ball coming to you and a player running on to it, and judging whether you will reach it first and running and hoofing the ball up field...not exactly working on the large Hadron Collider.
Any keeper with a modicum of judgement could play this kind of game.
