Many keepers come and go as the flavour of the season. Gigi is simply the best keeper of all time for the standard he's maitained for a decade. It's not like he is the best keeper in Europe every season, but he's consistently up there in the top 3-4 when not THE best. I think that consistency is truly the mark of a champion. And Gigi is top as far as that goes. Not to mention, being a good guy to go with it.
