<3 . He has done Real Madrid's GK history.

he is best

1. Iker Casillas
2. Buffon
3. Julio Cesar

these are 3 world class GK's who are still playing atm

jc's done many mistakes with inter this season.

this year Neuer and Hart were the best..
But my favourite is Iker..
He made amazing saves,especially for spain!

For me the best GK in history that are still playing are Casillas and Buffon, the best Gk in history is Oliver Khan and maybe Gordon Banks (I didn't saw him playing, but my father and grandpa tell me stories about him) and the next best Gk could be Hart and/or Neuer.

Legend.

one of the best goal keepers in history... probably in the top 3 spots of all time

1. Casillas
2. Schmeichel
3. Kahn/Buffon

Casillas  would be my  No1 keeper if i had to choose.

i completely agree with gunnergo
