everyone has a reason to win, Roma had reasons to win and Mourinho also had reasons to win
but unfortunately it never goes as "we want" and the winner is only one
I saw the game a bit and ball possession was Sevilla's, an indication that they managed the game
moreover, Roma used long balls hoping to catch their attackers
so it was almost a foregone conclusion as a result
so Sevilla happen because Sevilla is better
In the final, there have been so many pros and cons regarding Sevilla's victory, but like it or not, we admit that Sevilla mentality in the Europa League is beyond doubt. Even though I expect Rome to rise as a trophy winner. Dybala sadness seemed to be in the spotlight because seeing how he struggled throughout the match needed to be appreciated. Fate was still not on Rome's side and had to swallow a bitter defeat.
No doubt with Sevilla has bad perform in La Liga but success won UEFA Europe League this season and make them qualify to Champion League next season. Actually, Sevilla is not favorite team for winning Europe League because many people favored Arsenal and Manchester United are favorite teams will winning Europe League. Can't compare with domestic league performance and Europe League because Sevilla has experienced won all Europe League participants.
Its great achievement for Sevilla won 7 Europe League tittle, Sevilla won all Europe League final participants and impressive record with La Liga team when their perform in domestic league very poor.
You are right that even in La Liga Sevilla did not appear as serious as in the Europa League competition. No one would be surprised how strong Sevilla's DNA is in the Europa League. Seeing from the beginning Sevilla appeared in the Europa League until they reached their peak in the Final 50% of them locked in a win even though the opponent was Roma. They have won 7 trophies which makes the next season quite interesting as many Premier League challengers like Liverpool and Brighton can show resistance.
