Who is the best goalkeeper?

I would say a tie between Iker Casillas and Gianluigi Buffon. Iker Casillas because he captained spain during their euro 2008 win but im leaning more toward buffon because even though italy didnt win the euro he practically carried the team through it. He also had a fair few great performances durin the 2006 world cup. behind these two i would say chech based on skill even though i think hes a bit off form at the moment. i havnt heard dida's name mentioned for a fair few months so thats why i didnt pick him, Van Der Sar is getting old it has to be said. Frequent injury has put him off the starting line up and hes retired from the international squad. Toldo the same hes getting old and i havnt heard his name mentioned for a fair while. i think he is past his time. Valdes and Reina are both solid keepers but i dont think they are the best. Evidence that Reina isn't the best is the fact Casillas was picked over him as Spain's keeper which you could feel sorry for him because thats tough competition
