I doubt Sevilla will be able to make it to the semifinals, the victory over Fenerbahce slightly opened up the opportunity to qualify for the next round. His performance this season has been very far from expectations, in the local league they are still stuck in 17th place. Sevilla will find it difficult to face teams like Arsenal, Manchester United and Juventus, their performances this season have been much better than Sevilla.
Strong teams will survive at the end of the tournament, this season's Europa League has a bit of a UCL flavor if a team that often enters the UCL is able to step into the final.
Manchester United is currently in a weird situation after they lose the game against Liverpool and we can't be sure which team is going to win even Arsenal and Manchester United face each other but this can definitely be an amazing game because this manchester Unite with Ten Hag can make a problem for Arsenal even if Arsenal is in a good situation with Arteta.
