I dunno probably the quality of keeping isn't as good as it was 10-20 years ago, since without a doubt no keeper except for Buffon comes close to matching Schimichel (spell check). I agree about England, but i guess you are being a bit harsh on keepers in Europe or worldwide, if i was to pick a 10 based on ability:
- Buffon
- Cech
- Casillas
- Reina
- Khan
- Lehmann
- Ricardo
- Vander Sar
- Coupet
- Given
Thats a pretty classy list. Obviously the likes of Khan, Lehmann & Van der sar aren't as good as 2-3 years ago given their age but they are still pretty solid once fit.
Let's go through this lot one by one.
Buffon is just generally over-rated, he is not particularly poor in any one particular area, but I've never seen him do anything spectacular (don't watch the Italian league tbf, only CL), and I've seen him make a few mistakes.
Cech has to be the worst top-flight keeper, when it comes to crosses (or any loose ball in the box, as he showed against Reading), that I've ever seen. I've lost count of the amount of crosses he has missed and got lucky with either the striker missing or a defender bailing him out. Makes the odd good save, but misses the odd easy one too - West Ham last year CIP.
Casillas is over-rated basically on the back of trying to make every save he makes look spectacular. He'll make a meal of an easy save, and because it looked good, pundits will bang on about how many times he's bailey Real out. Er, no.
Reina isn't particularly over-rated really, he's not rated highly enough. Very good penalty saver (despite cheating at it), not great apart from that, and he isn't really rated as such - just a reasonably solid keeper, wouldn't have been close to top 10 in the world (which is what I assume your list is an attempt of) 10-20 years ago.
Khan was an exceptional keeper in his prime, no doubt about that whatsoever, haven't seen him too much in action lately, but given his age I would be surprised if he is still that good.
Lehmann is a keeper I have a grudging respect for, because as a person he is an absolute ****bag. When he first came to England he was very unreliable, however mistakes have grown less common recently, and incidents like the one against Fulham are now the exception, not the rule. That said, wouldn't be in a top 10 list 10-20 years ago.
Ricardo - my best look at him was in the 2006 World Cup, impressed me somewhat against England, not against other sides.
van der Sar - see Khan. At 38, he is not getting any younger, and proved to be an extremely untrustworthy keeper at the back end of last season.
Coupet - not going to comment too much on him, but I emphatically do not rate Barthez and up until his retirement he was still keeping Coupet out of the French side, albeit in controversial circumstances.
Given is a good, solid keeper, but really, is he that good? Arguable, but not top 10 material IMO.
