What a horseshit comment. Would being good at both violate the laws of physics? The top GKs in the world - Neuer, Lloris, De Gea, Courtois, Buffon, etc are good with their feet and are brilliant at the conventional goalkeeping skills. Literally every big club in the world has already moved to this type of GKs. You're living in the stone age if you think just saving shots will get you a starting position at clubs like Mardid, Barca, Bayern, Atletico or Juve.
by the way Ederson and Pickford can also save a shot or two hahah
