Congratulations Arsenal you got away with an uphill battle. I think in some league games you are very good and that will continue into the UCL. But I was wrong, Porto is quite strong. Porto made Arsenal difficult. They worked hard and made it to the penalty. In the penalty I was quite amazed by Raya's performance. He managed to thwart 2 penalties. Of course this will be history, because they managed to qualify for the quarter-finals.
It looks like Arsenal still have a chance to go further as well like qualifying for the semifinals but yes, if Arsenal not get a more difficult opponent. Because I think, considering about the teams that qualified for the quarterfinals such as Dortmund, Atletico, Barcelona and PSG then thus, it looks like Arsenal will still have a good chance of qualifying for the semifinals if Arsenal meet one of the teams I mentioned it. But yes, if for example Arsenal meet opponents like Real Madrid, Bayern Munich or Manchester City, then it will make it difficult for Arsenal to qualify. But indeed, any result can still happen but yes, because at this moment Arsenal are still in a good trend, then at least Arsenal will still have a good chance to be able to advance further.
