How this can be a shame for Roma when they lost the game to Sevilla because they had a perfect performance in this game and I think regardless of their own goals Roma could readily even beat Seivvla in this game.
Also, Sevilla is not a weak team and they are known for their performance in Europa League in the previous seasons.
I also agree that it is definitely no shame at all if you are in the final of the UEFA Europa League and then you lose it to FC Sevilla, the club that has won the Europa League more often than any other club. So AS Roma can be pretty proud about how far they have come in this competition. No doubt about that.
I do think though, that the way AS Roma came that far was really really questionable. Especially in the second leg against Leverkusen Rome played a horrible style of football. Not only did they play extremely defensively over the whole 90 minutes they also played very unfair by wasting at least 10 minutes in the second half alone.
