If the club were really going for it, aiming to be the most successful club in world football as quickly as possible, wouldn't anyone else be a bit...underwhelmed by Rafa? He did a really good job and he was far far better than Mike Ashleys Newcastle, but is he elite level these days? I cant think of many better but Nangelsmann, Pochettino or Allegri would probably be better fits for a club with potentially unlimited resources. Whether they'd come though, is another matter, perhaps not.
