Hopefully, next season, Roma can have more luck, because basically, in the Europa League next season, there are also teams that Roma should be wary of, such as Real Betis, Aston Villa, and Porto. So, Roma must prepare themselves as best as possible from now on if they want to win the Europa League next season. The Europa League will still be quite fierce, even though some of the teams we've seen so far are not the favorites, but they can all pull off unexpected surprises in the Europa League. So every team must have the ability to become better without underestimating any opponent because all opponents will definitely try to become champions in this competition.
They were probably the best team in the second half of the season, so it's clear that they are doing a good job. Only downside was that they started the season horrible which caused them to finish not at the top, if we only looked at the second half, I am sure they might be even the best team, didn't calculated but seems like a possibility.
That means, if they start being good from the first game this season, they actually do have a chance to make it happen, and that's what matters. If they deal with it as good as it gets, then we could see this be a lot better. So focus on getting the best player you could get, and just let the game come to you from the start. If they have to start bad and then recover, it will not be easy.
