After suffering a ridiculous sending off last night, Arsenal striker Robin van Persie admits ref Massimo Busacca had "a shocker" in Barcelona.
The Swiss official rashly sent off Van Persie at the Nou Camp in a 3-1 defeat that sent the Gunners tumbling out 4-3 on aggregate.
Busacca also awarded Barcelona a penalty that was dispatched by Lionel Messi to seal the Spanish side's progression to the quarter-finals.
This morning, Van Persie tweeted: "Thanks all AFC fans 4 tonight played vs a great team and a even better ref.
"He had a absolute shocker tonight think we all agree on this 1"
