A Lionel Messi-inspired Barcelona knocked Arsenal out of the Champions League for a second consecutive season as a 3-1 second leg win over the 10-man Gunners wrapped up a 4-3 aggregate victory.
Messi made the most of a Cesc Fabregas mistake in first half stoppages to break the deadlock, but a Segio Busquets own goal put Arsenal back ahead in the tie on aggregate. Robin van Persie was sent off after kicking the ball away when on a yellow card and Barca added further goals through Xavi and Messi's penalty.
