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.
If I'm not mistaken, the last time Arsenal qualified for the quarter-finals was 11 years ago and that's a long time for the Gunners to penetrate this zone. What they did paid off and their efforts were not insulting at all. The victory against Porto on penalties was still quite tense and maybe if it weren't for David Raya then Arsenal would have definitely been eliminated.
