I think this result was the matchup of the two strongest teams in the qualifiers. Porto and Roma are both strong teams and their struggle will continue. A draw is the strongest possibility in these matches because we can say that both teams are strong. Roma is on the rise in the Italian league and I think they will work as hard as they can for these matches they will play in the European league. My favorite for the European league is Tottenham right now. I think they are good enough to be champions.
I don't know the Porto team, i do not follow this team in the relative championship, however Roma currently has several problems and it does not seem to me to be such a stable team that can afford to win something this year.
The last game in 2021 they draw 1 - 1, but Roma is another team insteed today.
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.
