It was a good confident win by Arsenal who would had many other chances to increase the score line including a penalty miss by Mesut Ozil.
But most importantly Arsenal won the game and are top of the group by three points. Arsenal play the last group game away to Naples.
This group really was the group of death because despite having twelve points. Arsenal still need at least a draw from the game against Naples to qualify for the knock out stages.
Elsewhere Chelsea lost away to Basel by one goal to nil. But have now qualified for the knockout stage as other group results went there way.
It just goes to show that sometimes it really is the luck of the draw:)
