For Arsenal to get a draw while playing at the Emirates Stadium is actually quite bad. Because they know that in the second leg when they play at their opponent's home ground, namely at the Allianz Arena stadium, it will be more difficult for Arsenal.
The Allianz Arena is for jokes and the Bavarians tends to take every action serious and ready to execute their best performance against their opponents, though Bayern Munich are in pretty bad shape. Arsenal screwed their chances of qualifying for next round because how do we explain this scenario to gamblers and viewers? Outstanding form of Arsenal shared points with deformed Bayern Munich. This is basically one of the terrible reasons why I'm not sticking to believe in every moment of Mikel Arteta and this will continue to happen until they're able to maintain consistency.
