Regarding what we from Sevilla in this season, they had this team didn't have a performance at all in La Liga but the fact about Sevilla is they are usually successful in Europa League, and Sevilla once again win the trophy while they were not stronger than most of the other teams like Roma and Manchester United.
If I'm not wrong, I think Sevilla won the title seven times, and winning this tournament for seven times is a great achievement for any team.
it's all thanks to the experience of the Sevilla players at UEL, there are so many that the final match against Roma has a very experienced coach but in reality the coach's experience is not the key to victory but victory or defeat depends on the team's players.
and finally Sevilla who were able to win the 7th European league title even though they didn't have a great coach like Mourinho but Sevilla's players were able to appear solid to bring victory to all the fans.
