Arsenal angry at Barca defeat

Arsenal were left fuming with Swiss referee Massimo Busacca after being knocked out of the Champions League by Barcelona.

Busacca sent off striker Robin van Persie and awarded Barca a crucial penalty in an exhilarating final 45 minutes of their last-16 second leg at the Nou Camp.

With Arsenal holding a 2-1 lead from the first leg, Lionel Messi produced a brilliant late first-half leveller. Sergio Busquets' own goal restored Arsenal's lead only for Van Persie to be harshly dismissed for time-wasting, before Xavi's neat finish and a Messi spot-kick ended Arsenal's European campaign.
