The Gunners were outstanding but Mesut Özil in particular put on a special performance scoring his first goal of the season and setting up Alexis Sanchez with the opening goal.
Özil has often been criticised with disappearing in big games and to be fair it is not hard to see why. After all this was the World Cup winners first goal and second assist in 17 matches against the Gunners biggest opposition; Chelsea, Manchester City, Manchester United, Bayern Munich and Borussia Dortmund.
The 26-year-old defied his critics against United and put on a confident performance showcasing his quality in arguably the Gunners most important game of the season.
A loss for Arsenal would have left the north London based club in mid table and added to a disappointing week that saw them lose 3-2 to Olympiakos at home in the Champions League.
Özil will have to perform at this level consistently in important games to really shake off the criticism that he can’t perform under pressure but he at least proved that he has the ability to shine on the big stage.
