Yeah overall Arsenal played well in the Champions League, even though they lost in the last fight Arsenal performance was still pretty good and Inter Milan can be called Lucky scored one goal through a penalty. I'm sure Arsenal will go to the next round whether it is through a ticket or through a playoff, what is clear is that in my opinion the Premier League teams will take 2-3 places there Liverpool and Arsenal or Manchester City. There are only 4 matches left so that each team must continue to compete, especially the teams that lose many points in yesterday's match.
Arsenal and Manchester City are one of the best teams in Europe, yet they failed in this round. This might look bad but certainly their coaches will fix this issue and they will comeback in the remaining games.
In fact, this round has multiple bad results for other good teams, especially PSG and Real Madrid but also Leipzig, Juve and Bayer Leverkusen. No need to mention Aston Villa defeat and the silly mistake of their defender.
