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.
Seriously Arsenal was suppose to win the match, Bayern Munich which they played against haven’t really been performing well in their local league, they lost their last two matches before they played against Arsenal, and since they played at Emirates stadium, they should have just taken advantage of that and win the match, but they ended up playing draw, when Arsenal visit Bayern Munich at their home, the match is not going to be easy for Arsenal, and Bayern Munich will do everything possible to win the match, seriously they bought have equal chances to win the match.
It makes no sense if you were taking the performance from the domestic league as the strongest variable to determine how strong the club in UCL is. Things have not been going well since Bayern was trying so hard not to lose against Arsenal. Arsenal deserves to get draw against bayern.
People were predicting that arsenal would be destroying Bayern, but it's not even happening. Bayern can win the game even if the club will also be able to win it with a narrow score soon. The main weakness from arsenal has been spotted by bayern munich.
Arsenal is getting even closer to leaving the Champions League this season. The second leg is gonna be the die or alive match for both of clubs. I'm strongly believes Bayern can fully dominate it.
