I know people don't like resorting to stats, but this is one area that a sabermetric like analysis could be done and could tell us how good Reina is.
I think it's possible, but ultimately too much work for anyone not involved in the game to do, to analyse how many goals a keeper is worth to a team over the course of a league season. I am absolutely certain that nobody in the Premier League would come close to Pepe Reina.

I'm not sure how that would fair statistically, because relegation sides (and I realise our current position) usually have more shots to deal with, so the likes of Scott Carson (for example) could have a higher saves ratio.

It's much more detailed than simply looking at the number or ratio of saves made.
It would be a breakdown of every single shot and save made. Divided into zones on the field and in the goal. By analysing every bit of data over the course of a season you can determine how various keepers perform compared to the average overall and on particular situation. i.e. a ball hit from 20 yards out to the low right side of the goal.
You could build up a true picture of where keepers are strong and weak. Rather than just saying keeper x is shit cos I saw him flap at a cross last week.

Fair enough, it would probably then have to be broken down to simplify it, the amount of data would just be unreal. Like Keni said about concentration and pulling off a save when the keeper has had virtually nothing to do all game, so you'd have to consider stuff like that. Maybe a points system? I don't know. So many points for a rudimentary save, so many more for a more difficult save, so many more again for having to make a save after not being tested for a certain amount of time, etc. Difficult to measure, but interesting nonetheless!

It's a huge undertaking to do it, but it is the sort of thing that NESV brought to the Red Sox. But they have the advantage of only needing to do it for one country.
Imagine if we had the info and others didn't bother looking at it ? We're at a simply massive advantage when we go looking for a replacement Goalkeeper, or even from a strategy point of view by finding out where opposition goalkeepers are poor.
