Jennings was incredible. The best of his era, for my money.
Southall deserves more of a mention. If he'd peaked 10 years later, when Sky came into their own, he'd be getting far more votes in this thread.
Schmeicel (apologies for the spelling) was superb and he will get a lot of votes here because he's the one that we've all seen the most of. Undoubtedly, the best of the last 20 years, I think.
However, if both the great Yashin and Bob Wilson (who knows a bit about goalkeeping) nominated Bert Trautmann as the best, I'm only too happy to defer.
