That's some wild speculation there and I think I will go completely against it because arsenal don't have the tenacity to actually win the champions league yet although they have a great team and also playing pattern the winning power isn't just there and besides they were paired against their arch nemesis that always get the worse out of them which is Bayern Munich so they should first think of a way to eliminate Bayern Munich first before setting hopes for dreaming about securing the trophy.
You're still among those set of people that's underestimating the performance of Arsenal this season. It's been quite a boring road for this particular club but they're aiming to compete with flying solid strategy, not giving up because there's more to accomplish this season. This is one of the major reason why Mikel Arteta is doing a great job to ensured everything works perfectly for them this season but winning the UCL title, it's going to be a rough run for them but nothing is impossible to happen and nothing is also possible to be triggered.
Even me. I underestimate Arsenal this season when it comes to the Champions League because they lack experience players like Bayern Munich that will allow them to compete with them. I am just thinking Munich will continue to do what they did to them last season in the Champions League, but let us see if Arteta will do his best and have luck in defeating Bayern Munich, which will be extremely difficult because Tuchel is a much more talented coach than Arteta. If it's the Premier League, I believe Arsenal has a good chance of winning because they used to play the league all the time and know each other in clubs, but the Champions League is other clubs in various leagues, and Arsenal lacks confidence to compete with other clubs league very well. and am very sure even Barcelona face arsenal i will likely say xavi will defeat Arteta when they meet in the UCL, Because Xavi is used to the Champions League, he can exploit any knowledge to defeat Arsenal. Even the league title is pending let us see if they can defeat Manchester City in the league after the international break.
