I wud sooner say he was the last in the old breed of bad keepers. Dida and Julio Cesar are far better than Taffarel ever was. And Dida is a prolific pk stopper, Taffarel made his name as a pk stopper off the back of 2 games - the 94 WC (although it was Baggio dat missed rather than him saving) and the UEFA Cup 2000 shootout. I found him very erratic otherwise
Having said that, he was playing behind a very suspect defence for most of his international career. Its only recently that Brazil's defence has become respectable.
Taffarel got a rep for being a penalty stopper at the youth level (the olympics).
He was been around way before WC 94....The penalty that he stopped in 94 was Massaro's. Baresi and Baggio both hit over the bar.
Brazil kept a clean sheet in 5 out of 7 games in WC 94. (same number of clean sheets as Zenga in Italia 90) If that is a record of a suspect defence, then I don't know what to say about most defences in world football.
Taffarel also saved 2 pks in the W.C. 98 shootout against Holland
Taffarel was criticized from time to time in the latter stages of his career, but for the most part was a well respected keeper.
