Unai Emery has achieved some big things since leaving Arsenal. He left the club with the team out of the top four race early in the season and with a dressing room at a fractured low point.
However, since taking the job at Villarreal, the former Arsenal head coach has won the Europa League, overhauled much of the team and now taken the Yellow Submarine to a Champions League semi-final. Their first the infamous semi against the Gunners in 2006.
