Arsenal would play Bayern Munich as an underdog in the UCL quarter- finals that means pressure would be on Bayern to win the match and it's obvious the present Bayern is not like the previous formidable team they had been on and of in term of their performances in Bundesliga , however the present Arsenal team can't be underrated notwithstanding there match against Porto which they narrowly won, Porto didn't give them the chances to play there usual free-flowing passes and not shaky Arsenal all effort to score more goals proved abortive and was thwarted by Porto defence manned by legendary Pepe whose wealth of experience helped Porto to stop Arsenal from scoring,
It is difficult to guess who will win in the match, although currently Munich are not in good form, but their motivation to get the Champions League trophy this season certainly deserves to be counted as favorites to win, currently Munich no longer have a chance of winning in the Bundesliga and certainly they will only focus on being able to win the Champions League trophy as the main target this season, While Arsenal are actually very burdened with their current busy schedule, besides that Arsenal are required to be able to maintain their performance well in the League and Champions League.
I personally will not underestimate Bayern Munich in the game against Arsenal, although currently both have an inversely proportional performance, but so far we know that it is difficult for Arsenal to be able to overcome Bayern Munich even though Munich is in a slump like the previous season, Bayern Munich has had a better head to head than Arsenal when the two met, With details of their meetings as many as 8 times in the Champions League, Bayern is ahead with 5 wins, 2 draws, and 1 defeat.
