In fact, I'm the opposite and don't even follow the developments of the two teams that will compete. As Roma vs Porto both have their own advantages which make it difficult for the opponent to beat them. Roma has a little problem in the team giving Porto more space to control the match without any burden, however these two teams are very evenly matched, it's hard to predict which one is superior.
Roma is not that strong and they're not stable but if they take this match very serious, they can achieve victory. Porto isn't a strong team too and I believe that whoever among these two clubs that can outplay the other will definitely qualify to the round of 16. I will both clubs have the same strength and it's a perfect match.
Matches like this are very hard to predict and also very entertaining to watch as compared to other games where one team is clearly seen as the better team and has the more chances of finishing the game better. The Europa League is a big competition also and I believe they will be playing for the progression of their individual teams.
The strength of both teams is indeed on a very neutral ground when compared to each other, but I still see the chances of Roma finishing slightly better ahead of them when they meet in this match. Although, we can’t come to a conclusion yet until the match is played, so I think we should just wait and see the outcome of this match which will be revealed soon.
