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.
Napoli vs Barcelona 1-1 and Barcelona's goal was scored by Lewandowski in the 60th minute, and Napoli's goal was scored by Osimhen in the 75th minute.
We can call it an unlucky day for Arsenal after several attempts ended in vain, but even if Porto win today they are not safe yet because Arsenal can turn things around in the next match we also know Arsenal can beat anyone who comes to their home base. Napoli and Barcelona only played a draw even though Barcelona dominated, they couldn't win it. The results of today's match are almost the same as yesterday's match and each team still has a chance in the second leg match.
Yes, even though Arsenal had taken 7 shots but none of them were on target so Arsenal had difficulty scoring goals, this was because the home team had anticipated playing a fairly good defensive strategy and Porto succeeded in playing this.
In the second leg, Arsenal still has the opportunity to counterattack because Arsenal played very strongly at home, but Porto will use the same strategy as before, namely maintaining a tight defense and we'll see if Arsenal can get rid of Porto in this round.
Yes, the results of the first leg are only Man City and Madrid who are guaranteed to qualify because they both won when they visited while the other teams still have the same chance in the second leg.
