Yes, Arsenal are very strong at the moment and the game against Bayern could well prove to be a winnable game for them. So far I don't see Bayern being able to beat them or win the Champions League in general, they have a series of bad games in the context of their home league. But it will be a tough match for both teams either way
It's true, the match between Arsenal versus Bayern Munich is a very troublesome match for both teams. Arsenal is in stable condition, so their chances of beating Bayern Munich are quite open. On paper, Bayern Munich is a team that deserves to be favored based on their experience, they have a better mentality compared to Arsenal in the Champions League. Thomas Tuchel squad can show a different performance in the Champions League, even though they are currently experiencing a decline in performance in the Bundesliga.
Arsenal has no good head to head against bayern and this shall become a very important thing that needs to be anticipated. Bayern was also very often in beating its opponent with huge scores in the past but things are very different when it comes to the this season. Bayern has been performing so badly in the domestic league and this is also greatly impacting the performance from the club. Bayern needs also to make sure it will not bottling this game. The first leg is gonna happen at emirates stadium and this gonna be a hard test for bayern. Bayern is not yet in good shapes and im expecting bayern to lost with narrow score against arsenal soo.
Bayern can win the game if club will able to win against arsenal in the first leg.
