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.
Now both of this ties are heading to the second league with a tight score. Porto defy odds to upset an inform Arsenal team that has scored more than 10 goals in the last two matches, only to fail to score even one in this fixture. They fail to even get a shot on target throughout the match even though they dominated in possession which shows how compact the Porto defense were. They need to do more when they travel to England to visit the Emirate stadium. In as much as this is the champions league I will still predict Arsenal progression to the quarter finals because Porto away from home to English clubs is a poor place to be for team.
As for Napoli and Barcelona I think this was already a game that couldn’t be predicted because of the nature or form both clubs are in and the game showed that. The second leg is going to be more of what happen today and any of the team that utilizes the chance that will be minimal that day will be.
