Porto vs Arsenal 1-0. Arsenal as a whole dominated the game but Porto's very strong defense made it difficult for Arsenal to score goals.
And Porto's 1 goal in the remaining extra time scored by Galeno in the 90+4 minute was a painful goal for Arsenal.
Even with Arsenal's best efforts, Porto scored an extremely unexpected goal in the agonizing extra minutes of the game, and they went on to win 90+4. But in all seriousness, the match is extremely demanding, which is why both teams find it so difficult tonight. I'm in much more agony over the fact that Arsenal had numerous scoring opportunities but were unable to take advantage of them because of the pressure Arsenal faced from Porto. Arsenal genuinely wants to avoid what transpired during their most last match against Porto.
That's why they try to win the match, they maintain their consistency and put up a powerful display, and Porto held them off in the end. Later on in the game, Porto dominates with a single goal to seal the victory.
