Sevilla is the luckiest team I saw and they didn't have good players or even a good coach this season, also in most of the games, Sevilla couldn't even have a good performance and the only reason for them to win this title was using the mistakes other teams had and they also had enough luck to win the hardest games against strongest teams like Manchester United in this season.
That's why I can blame Roma and Mourinho for anything when they lost the game against Sevilla.
Sevilla was not lucky for winning the Europa League because they really deserve it but I think they were lucky not to have finished the season in the bottom place because they had a very poor outing this season they just managed to win few games with aver poor performance in every game I watched them this season. Did they win the Europa League using other teams mistake I guess no rather they saw the trophy as the only remedy to their problems and when they got to the knock out stages they changed their playing pattern and that alone helped them to defeat the big teams you mentioned and I think they are like owners of Europa because they never lost in the finals and winning it was a dream come true to so many fans.
I'm sick of saying it, Sevilla are like Real Madrid of the Champions League when it comes to competing in the Europa League Competition.
I won't say they're lucky, they deserve everything they had this season, the new manager helped thefans achieved something, after a disastrous, La Liga campaign, yes I'm aware thy still go to qualify for the Champions League.
Manchester United should have been winners, but they couldn't hold on to the both goals scored by Sabitzer during the first half. They cam back strong and more stronger with the return leg at home. They do deserve it, there's not piece of luck innit.
