It was not pretty, but it was the most important victory of Arsenal's season so far, and a vital one if they are to continue their current upwards climb.
The Gunners saw off a dogged yet wasteful Besiktas side, with a 1-0 win at the Emirates Stadium.
A single goal from the Turkish side would have knocked Arsenal out on away goals and there was no room for error.
German international Mesut Ozil used his Twitter page after the game to send a message to fans, 'winnning - no matter how' was what was important.
Ozil himself is still finding his form after joining the club late after the World Cup, and played all 90 minutes in the victory.
He completed only 79 per cent of his passes, a low figure by his usually exceptional standards, but still carved out two goalscoring opportunities.
How do you think Ozil played in the win?
