If you see the game, Arsenal may be much better, but Bayern Munich has experience when they are under pressure so they are able to run the match even though Arsenal is enough to press and Bayern Munich's ability in a match that ends in a draw is also inseparable from their experience as one of the clubs that often Playing in the Champions League. Although the process they were a little successive because they got a penalty on their second goal.
This experience thing that we used to determine the unplay match is not necessary because a team can lack a defensive midfield and makes penetration easy for their opponents, they can have good forward with failed midfielders and with that, they can hardly score. During th course of the match, they can also have any red card if any of their players made an obvious too foul. This is why I don't put experience in performance as yardstick for a team to win a match.
Now Arsenal must return to focus on the English League because competition there is not much more important. Leading the standings with the same points as Liverpool has not made them safe so Arsenal must focus on the next match when facing Aston Villa.
They should do all the have to do but the same energy they have, Manchester City have 2 times of that and that's why I believe they will overtake Arsenal in this match. Remember that Aston Villa won them the last time they met and they are also trying to push further in the table because of Tottenham is now having the same point with them, this is the perfect opportunity for Aston Villa to win Arsenal is you ask me
