As Champions League ties go, you won't get many as controversial as Arsenal's 2-0 defeat to Bayern Munich at the Emirates this evening.

From start to finish the game wasn't far from a controversial moment, particularly in the first half where we saw two missed penalties and a red card for Arsenal's Wojciech Szczesny.

The red card was the big game changer, with the Gunners having to play over 50 minutes with just 10 men, but many thought Arjen Robben dived in the challenge that lead to the Polish stoppers dismisal.

So here's the five big controversial moments from tonight's Champions League action from North London...

1. Mesut Ozil's poorly taken penalty means Arsenal blow a big chance to take the lead. But why was he the one taking it?
