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 is the most luckiest team in the Europa League sometimes I imagine how they end up defeating strong teams in Europa League. I don't see Sevilla squad better than all the team squad in the Europa League but they are too lucky to win their games in the league. For Sevilla to win the Europa League it is a surprise because the performance is poor.
