Arsenal lost both in the league and the Champions League.
I don't think this point loss and defeat is good for Arsenal because they could have found morale in this match.
Aston Villa won today, if they continue like this they can participate in European cups if they rise to the upper ranks.
Arsenal had long since fallen behind Liverpool in the English Premier League, so they had given up their dream of winning the Premier League title, but they expected to do well in the Champions League, so they planned well for the Champions League, but that plan did not work for them because they lost 1-0 to PSG. The first leg match was held in Arsenal's home round and their defeat there was undoubtedly a big loss to PSG.
After a few days, the second leg match will be held, where Arsenal has no option but to win by a big margin. If Arsenal cannot win by a big margin, then they will lose against PSG and exit the Champions League. Arsenal has been performing well since the beginning of the season in the Champions League and they have also defeated Real Madrid in multiple matches, but now I don't know why they are unable to pass PSG's test. Best wishes for the second leg match.
