I get the impression from many things that have been said during Rafa's reign that he is very hard to please, almost never satisfied, always looking for ways to improve. That is great. Provided you give the players the necessary encouragement and support along the way. That is my worry with statements like this from managers. It suggests that they want all players on the edge constantly rather than encouraging them to do better. Spurs are a classic example of the eventual outcome of this sort of policy. Same bunch of players but two different management styles. From what we are bieng told Harry said he would take no rubbish, you will play like this BUT he also encouraged the same bunch of guys who had looked absolutely usless and now look at them. It is all about man mangement and I just hope Rafa also has the encouragement side to HIS game, along with the perfectionist side.
