The FA needs to take action against referees who make mistakes often. Especially Martin Atkinson. He made a lot of really crucial mistake, most recently at the Emirates, where he disallowed a goal just to give Sagna a yellow card. In 2009 he was accused of bad time-keeping. The fourth official signaled 4 added minutes of injury time, but Michael Owen scored in the 96th minute, handing Manchester United a 4-3 win in the Manchester Derby.
