Sevilla are known to be very strong in the Europa league every season, they have quite a long experience in this competition even for this season they performed relatively well in the Europa league but it's different in Laliga where they are still struggling to improve their ranking in the standings table because currently Sevilla are in 14th place in the current standings.
for Manchester United they are indeed strong candidates to win the Europa league title this season if you look at the depth of their squad which is filled with good quality players, but in the H2 meeting of the two in the Europa league Sevilla was able to dominate victory against Manchester United. So, will Sevilla make another surprise against Manchester United?
Inconsistent performance in domestic league not bring negative impact for Sevilla because success qualify to quarter final and face with Manchester United, I doubt Sevilla experienced with most winning UEFA Europe League keep continues because in the next stage have waiting for by Manchester United.
The Primer League keep consistent performance this season and success eliminated Barcelona in playoff round and Real Betis at 16th round become capital for United against with the La Liga team up coming next round. I sure with twice winning from La Liga team, Manchester United have understood well about the weakness from Sevilla and potential lead to semifinal Europe League.
