If Roma manages to beat Porto, it will be good for Ranieri who might have a chance in the next round to advance further in the Europa League. And for Serie A, although there is no target for the trophy, at least Ranieri must push Roma's performance to rise in the standings. At least they must occupy a position where they get tickets for European competitions.
Roma's points difference with the teams that are at least in the top 6 of the standings is quite far. So it takes a lot of effort to be able to push Roma up the position.
At the beginning of the season we saw a weak Roma team. But gradually Roma has been able to improve their performance a lot. And at the moment I think it is difficult for any team to get full points against Roma. In the last match of Serie A, a strong team like Napoli failed to win against Roma. Roma is unbeaten in the last 5 matches in Serie A. Roma has won in three matches.
Roma team is in good form. So it can be expected that Roma players will be able to perform well against Porto. I am optimistic about Roma's victory. Also, Porto team is not in good rhythm now. Porto has failed to win in the last four matches of Liga Portugal.
