CESC Fabregas has shouldered full responsibility for Arsenal's Champions League burn-out in Barcelona and apologised to Gunners fans.
"I take full blame for the result tonight," Fabregas said. "One of the worst moments of my life. I apologise."
But while Fabgregas gave a lesson in losing gracefully, Arsene Wenger and red-carded Robin van Persie moaned and groaned about referee Massimo Bussaca and blamed him for the 3-1 (4-3 agg) defeat.
It was Fabregas who gifted Lionel Messi the opening goal via after a suicidal back heel near to his own box.
But within minutes of Arsenal's equaliser, an own-goal from Sergio Busquets, van Persie, already on a yellow after losing his cool with Dani Alves, was dismissed by Swiss referee Busacca for time-wasting.
"We feel betrayed a bit, when it was 1-1 it was all to play for and in my opinion this referee killed the game," said Van Persie, clearly at odds with Fabregas, but not with his manager.
"I just spoke to UEFA people. They are shocked as well because it killed a promising, fantastic football match," claimed Wenger.
"What for? If it's a bad tackle or a second bookable offence okay, but frankly it is embarrassing."
