The worst I have seen officiating an Arsenal game in in the last few years was Stuart Attwell. The man had zero control over the players and was just ****. The FA thought he was so bad that he has been demoted to the Football league on a permanent basis and rightly so.
Lee Mason has improved remarkably but is still average. When he reffed our game vs Villa it was the first time I had seen one player barge another player and the free kick go in favour of the former. Just bizarre refereeing
