Can only say that maybe it's a dream that can be pursued. However, this opportunity will be more difficult compared to the EPL. Arsenal must have good preparations for the match vs PSG in order to reach the Final. With the potential to face Barcelona, this small hope must be used as motivation. I think Arsenal will secure the result if they score a goal. Defending as best they can to ensure the 2nd Leg, they still have at least 1 decisive goal to qualify for the Final. Winning the UCL will be the best achievement for Arsenal after a long time not winning both leagues.
Arsenal have not managed to reach the final again for quite a long time. And Arsenal actually reached the UCL Final for the first time, right? namely at that time in the 2005/2006 season. At that time Arsenal faced Barcelona. And at that time Arsenal lost to Barcelona in the UCL final with a score of 2-1. And now Arsenal and Barcelona actually have the potential to meet again in the UCL Final if each team manages to beat their respective opponents. And it will repeat the history of their meeting in the UCL final like in 2005/06.
Meanwhile, the last time PSG managed to reach the UCL final was in the 2019/20 season and at that time PSG lost to Bayern. But I have a feeling that Arsenal will make it to the final. It's just that PSG, with its high aggressiveness in attacks, could really overwhelm Arsenal. Because Liverpool and Aston Villa have felt it. I hope Arsenal makes more thorough preparations. And you can't lose like Liverpool and Aston Villa.
