To be honest, Porto's recent victory over Arsenal was largely due to luck; Arsenal's performance flagged as the game was about to end, Otherwise I doubt they could have scored in that match, as Arsenal played with great intensity in both the first and second halves. Everyone had a hard time seeing a goal because they both thought the game was really challenging.
However, given how well Porto has played Arsenal at home, I don't think they can duplicate that performance in the second leg. That being said, even though Arsenal is formidable at home, Porto will undoubtedly find the match extremely challenging.
Yes, this could be said to be luck for Porto because Porto managed to take advantage of the opportunity when the visiting team's performance began to weaken in the final minutes of the match and Porto used this situation to break through Arsenal's defense so that Arsenal had to suffer a fairly painful defeat in the first leg, because as far as We know that throughout the match Arsenal were better at controlling the ball in the middle of the field but thanks to the intelligence of the Porto players they were able to keep their defense tight so as not to concede a goal and Porto also tried to create opportunities even though they were a little late but this could be a help for them to jump in. second leg.
This big competition is indeed very challenging for anyone who plays in the Champions League. There is not a single club that underestimates its opponents in any round in the Champions League because sometimes clubs that are not favorites are able to provide surprises, we also don't think that Porto can beat Arsenal because as far as I know Premier League clubs are very strong, therefore Arsenal will avenge their defeat in the second leg because Arsenal performance at home is no longer in doubt in winning the match.
I wasnt convinced at first, especially given the predictions that Arsenal would easily beat Porto. You and I know football is unpredictable. Porto's fans' passion after the score changed the mood, showing how important home support is in tight games. Its a monument to Portuguese football's character and culture, which excels in Europe despite financial constraints.
Im bullish about Arsenal's home prospects in the second leg. The Gunners have a good habit of winning in front of their fans. Their middle-field play proves they can dominate the game, as you said. This time, its about turning control into goals.
