Off one incident.
Felt this way for about a decade. Theres a whole bunch of them who jump around like a fish out of water when a shot comes their way, but end up just flapping a hand at the ball or getting nowhere near it. Obviously there are exceptions like Buffon/Peruzzi, but the standard below a handful of world class keepers tends to drop very quickly - alot better in the Premiership imo where you have good keepers at even mid table clubs.
Mind you, some of what I'm referring to from the past could just be the result of match fixing in Serie A.
