He actually changed it,doing it this way will influence next generations of GKs .he took it to a whole new level and it will be taught to young GK prospects .that is the reason he gets hype .b/c while he isn't better that Buffon/Casillas at their prime he is a one who will affect goalkeeping for future
RM media tried to hype him ,they tried it again in 2012 too .but with Xavi&Iniesta it wasn't him gaining such momentum that Neuer has now .he doesn't simply have a competition from fellow Germans,Muller ain't that good tbh and all of Germans are hyping him
