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.
I think the chances are still 50:50 because both teams have not performed too impressively throughout this season. Roma's defeat to Milan in the last match proved that their defense is still very fragile, perhaps both teams will score goals in this game. Before facing Roma, Porto will also face Sporting CP in the domestic league, which will drain most of their energy because if they lose, their position is threatened to be taken by SC Braga.
This is home match for Porto which i am sure they will be targetting win result but Roma also in the good shape especially after beat Frankfurt in this competition and draw from Napoli which these record have proven Roma has good progress under Ranieri so i will assume Roma will attempt not to lost from Porto and displayed defensive strategy
In the term of schedules i can see Roma has more hard compared to Porto because after fight against AC Milan on Coppa Italy Roma has a match against Venezia in Serie A this Saturday but i am sure they can able to beat Venezia and about the match against Porto i think it's hard to predicted but i just thinking there is possibility the match will ended to draw
