From this match it was clear that Arsenal dominated the game and they also managed to score the first score. Actually, if we look at Arsenal's performance then victory is in sight. Luckily, Bayern Munich got a penalty kick so they managed to make the result end in a draw. If Bayern Munich didn't managed to take advantage of this opportunity, Arsenal emerged as the winners. I am sure that in the second leg Arsenal will use their full strength to snatch victory from Bayern Munich.
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.
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.
