A bit of constructive critisism here and there never hurt anyone but he makes it out as if the refereeing staff are out to get Manchester United, yet when comments are made against decisions that benefit his team, he throws a paddy. The referees are just doing their job and at the pace of the way the Premier League is played, it is easy to make one or two mistakes. Ref's not long ago were critisised for not giving enough advantages and stopping the game too often, but now that they are giving advantages, they are critisised for missing vital decisions, they just can't win. I feel sorry for them really.
