And Porto's 1 goal in the remaining extra time scored by Galeno in the 90+4 minute was a painful goal for Arsenal.
Napoli are lucky that the Victor Osimhen in the just finish African cup that missed many good chances is not the same Victor Osimhen in Napoli who scores with the slightest opportunity. His goal stole the joy away from Barcelona.
Nonetheless, FC Porto indeed has a peculiar Champion League experience, but not as experienced as Asernal so this loss for Arsenal is a big setback for the club this season.
It's not entirely shocking that Porto managed to defeat Arsenal, despite Arsenal appearing to be in better form when you look at their performances in their respective domestic leagues. This is because Porto has also been performing well, especially since they were played at home. With the advantage of playing on their own turf, Porto came into the game with a strong presence and a solid strategy, which ultimately led to their victory.
Additionally, luck might have played a role in their win. Now, Arsenal needs to put in extra effort and work diligently to bounce back and secure a win in their upcoming matches. Considering the circumstances, it's a bit skeptical to assume Arsenal could have easily clinched the victory, even if the game were played at their home ground.
