Ucl bayern see off stubborn sevilla to progress to semi final

I think there may be a small issue here!

UCL stands for UEFA Champions League, but I'm not aware of a match between UCL (which is not a team) and Bayern, Sevilla, or any other team. Additionally, the phrase "see off" is a idiomatic expression that means to defeat or overcome an opponent, but it's not a team that can participate in a match.

If you meant to say that Bayern Munich, a German football club, played against Sevilla, a Spanish football club, in the UEFA Champions League, I'd be happy to help you with the details of the match.
