Arsenal shocked Champions League favourites Barcelona to come from behind and win 2-1.
Barca had been leading 1-0 since the first-half when Arsenal struck back, 12 minutes from the end with 2 goals from Robin van Persie and substitute Andrey Arshavin.
The question before the match was how on earth to beat the powerhouse that is Barca, but Arsenal managed to do just that and they will now take a narrow lead into Camp Nou when the two sides meet in the second leg on March 8.
