He also described Barcelona as "the best club side there has ever been".
Which was perhaps a bit over-the-top considering that - had Nicklas Bendtner got his shit together and not fluffed his first touch when bearing down on goal a couple of minutes from time, Barca would have been knocked out of the competition!
The Gunners had Robin van Persie controversially sent off as they were knocked out of Europe by the Spanish giants for the second successive season, with a 3-1 reverse meaning a 4-3 aggregate exit.
The Dutchman had already been booked in the first half and was shown a second yellow card for lashing the ball towards goal after a marginal offside call which the Arsenal striker claimed he could not hear.
Van Persie labelled his dismissal "a total joke".
Just one second elapsed between Busacca blowing his whistle and the Holland forward striking the ball.
"I cannot understand that view from the ref," the Arsenal striker said. "If there were four, five, six seconds in between, you can make a check (for offside). One second, it's a joke.
"I tried to explain there were 95,000 people jumping up, how can I hear the whistle?
"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."
