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 was on edge when Porto capitalized on Arsenal's late-game slump. Arsenal's midfield control seems solid, but Porto pulls a fast one. The Champions League is unpredictable and fascinating because of these situations. Arsenal is known for their home strength, thus the second leg will be exciting. I think UCL experience matters, and Arsenal may be younger than Porto. I trust Arteta's team. Arsenal's play has been excellent, and I think they'll win at home. They must, right? Anything less would surprise us fans
