Mikel Arteta is doing good job and his strategy is having good results for him which are clearly indicating they are on verge of changing history and going to have their best in this event after decades of bad results, Arsenal is now clearly looking for the success in all events.
I can also put Arsenal as favorites in that match. Arsenal has changed a lot and is no longer a mediocre team in the UCL. They have a solid squad this season. Mikel Arteta has succeeded in making Arsenal one of the best teams in the Champions League this season. They struggled against Porto and managed to escape after a penalty shootout. But Munich is also not a good team at the moment. Their performance in the league is not that good even though they are still in second place. Everyone still remembers their defeat against Frankfurt and the draw against Freiburg. I personally think Arsenal will be able to advance to the next round. They are not favorites for me to win UCL, but they are favorites in this quarterfinal match.
