I am not sure yet with Sevilla will rejoin Europe League this season because they dropped on 4th standings with one match left difficult to beat Lens just need draw to lock their position on Europe League. Seems excited if Sevilla can relegated to Europe League this season and waiting their journey will success defend the last season trophy or not? Whatever bad result for this season in Champion League, Sevilla still the best team in history their appearance in Europe League. Most winning trophies and need several years later for destroying Sevilla trophies on Europe League.
If Sevilla can't participants in Europe League for this season, I think still have Bayern Leverkusen with unstoppable winning trend and Liverpool have consistent performance in domestic league will be favorite team for winning Europe League trophy.
Yes, in my opinion, Lens has a better chances of qualifying for the European league compared to Sevilla because Lens is 3 point a head of Sevilla. In the last meeting in the Champions League, the two of them will compete fiercely and fight hard and will determine who will be relegated to the European League. We can also see if Sevilla can win the match against Lens because in my opinion Sevilla will experience difficulties because they are playing away from home because in the previous meeting Sevilla only drew with Lens when playing at home.
However in the next match it cannot be predicted with certainty but if Sevilla is able to give a surprise to In this match, Sevilla can fight again in the European League, which will be a tough competitor for Liverpool and Bayer Leverkusen in fighting for the European League.
It does look like Lens will join, Sevilla has better goal difference to be fair, so if they win then they may do better but at the same time we are talking about Sevilla playing against Lens on the last game, which means that everything will be based on that last game, if Sevilla ends up winning by a good margin then they could go to Europa once again and to be fair I wouldn't be shocked, they love that cup and they will do their very best to make that work, they are a tournament team and they are capable of getting a win here, Lens is better team right now but Sevilla is a team that won against many better teams before, and could be considering the situation like their last chance, which is true.
However, if they do fail, and Lens go back down, then Sevilla will be going back home, and Lens is not that much of a threat at Europa to anyone, Sevilla could be worse than Lens normally, but when it is about Europa I feel like they are more dangerous than anyone.
