Arsenal are the favourites to win this game based on their current statistics and how they've performed as a team to reach this stage. Bayern Munich has been struggling for quite some time now, and as a result, they have given up hope of winning the Bundesliga title this season so early after Bayern Leverkusen has taken the lead and is still maintaining their consistent league form. Arsenal is still one of the best teams in the English Premier League, and they are still contenders for the title while also performing well in the Champions League. Arsenal does not have a good record against Bayern Munich, but in this game, they stand a chance to win and make it to the semifinals of the Champions League competition.
The gunners are know to putting in that extra effort when they are playing from home because they cannot risk facing the embarrassment of loosing at home so they make sure they are getting a draw or they win their visitors but then in this case it's the champions league and then both teams aren't such that could be seen that either of them is weak but have got good abilities especially with their performance so far.
If Arsenal looses in this match it will be the end of the race for them in the champions league and it will be that it's over five times Arsenal had qualified for the champions league and has been unable to get to the finals , I'm just hoping arteta will be able to device a tactics to help them change the narrative they have had over a long period of time. Bayern Munich hasn't really been too good with champions league aswell, they have only in a few times gotten to the finals too so both team are fairly equal going by the records so far.
Personally I wouldn't be supporting either of both teams in this game because they both have good team depth and even a good performance in the champions league so far but Arsenal has actually had to struggle especially passing the most recent stage so it's making me feel Barcelona could be the winner except for the home advantage Arsenal has got which they may want to use against Barcelona.
