Achieving the three goals you mentioned is a daunting task for Manchester United, with their current status of injuries. They have managed to keep a clean sheet against Nottingham Forest in their recent match, but this victory alone cannot fully define their success in the upcoming match against Sevilla. Sevilla's performance in La Liga has been average, and Nottingham Forest is already out of the EPL season due to their poor performance. I am not entirely confident about Manchester United's next match against Sevilla, I will bet on the next match as over 1.5 because I know for sure that Sevilla will score a goal and Manchester United will also score a goal under regular time.
I am also not confident about United chances of winning Sevilla in Spain. United had the tie in their hands when they were 2-0 up and they blew it with two silly own goals in the dying minutes of the game.
Man United underrated Sevilla after the second goal, they felt it would be a walk in the park so they let their guard down, coupled with the injuries. The draw has most certainly kept Sevilla's hopes alive. They will feel like "if we can get a draw in England, why cant we get a win in Spain".
I expected nothing from Sevilla but they proved me wrong and they might just be able to knock out Manchester United despite their poor form in the league.
