There are few games in Arsene Wenger's reign as Arsenal manager which come close to the victory over Barcelona in February of 2011.
Arsenal had come into the game as firm underdogs. An under-strength Arsenal side had been taken apart by Barcelona in the 2010 Champions League, and the Gunners were desperate for revenge.
But wanting revenge and taking revenge against Barcelona are two quite different things.
The Catalan team dominated the first-half of the match, and were unlucky to only be one goal up at halftime.
Arsenal fought their way back into the game, and Arshavin immediately made an impact after he came on as a substitute in the 68th minute. He was involved in the build-up to van Persie's 78th minute equalizer, which set up a frantic last 10 minutes.
From a Barcelona corner, Arsenal calmly passed the ball out of danger. Fabregas received it, swivelled and sent a delicious through-ball to Samir Nasri.
Nasri received the ball, drove into the area and waited for support. Looking up, he saw Arshavin and passed the ball across the box.
Arshavin hit the ball the first time, curling it away from Valdes and into the net.
Cue utter delirium.
Arshavin ran to the fans, lifting his shirt over his head to reveal another t-shirt with a picture of himself on it.
The goal highlighted many of the features by which Arsenal fans will remember Arshavin: his individual skill, his eye for goal in the biggest of games, and, last but not least, his wonderful eccentricity.
