Bodø/Glimt has really performed very well in this season's Europa League competition, and nobody believed Bodø/Glimt would be able to pull off this performance and qualify for the semifinal, which they will play against Tottenham Hotspur next month. I would have loved to see Bodø/Glimt playing in the Europa League final just like you said, but I am not sure if Bodø/Glimt can beat Tottenham Hotspur and set up a Europa League final with either Athletic Bilbao or Manchester United. Since Manchester United will not qualify for European competition next season, I prefer Manchester United lifting this season's Europa League trophy, which will help them to play in next season's UEFA Champions League competition.
Bodø/Glimt have already achieved an impressive result, even if they fail to advance. And I think the winner will ultimately be someone from the other semi-final, so either Athletic Bilbao or Manchester United. Since Tottenham are not that good at the moment and concede a lot, and Bodø/Glimt are already dark horses and let's be honest, of the remaining four, they look the weakest, although in terms of game they may not be much worse than Tottenham or Manchester United, who do not have the best defense.
If I am not mistaken, this is the first time Bodø/Glimt have reached the semi-final of the Europa League, so I agree with you that Bodø/Glimt have already achieved an impressive result in the Europa League competition because they beat some good teams to be where they are today in the Europa League. Even though Bodø/Glimt is the underdog in the remaining 4 teams in the Europa League, there's no guarantee Tottenham Hotspur will beat Bodø/Glimt because Bodø/Glimt has been pulling off surprising results in the Europa League, and they are capable of doing so against Tottenham Hotspur.
