This season it looks like Union Berlin will not be as good as last season and there is no big hope for Union Berlin to stay in the UCL for long.
And next season it looks like they won't get another chance to compete in the UCL.
The Bundesliga is currently being controlled by really strong team so it will be difficult for Union Berlin to be at the top like last season when they got top four ranking.
It is natural that Napoli odds are quite profitable because the match will take place at the Berlin Olympic Stadium (Germany).
Union Berlin have lost their way this season and cannot target anything in the two best competitions they participate in, the Bundesliga and the Champions League. I thought the closest match against napoli would also end in defeat for them, even though I was surprised by their resistance in the first match against Real Madrid, they almost drew at that time. I also think that this is a very bad season for them, their performance is still inferior to promoted clubs Darmsdtadt and Heidenheim in the Bundesliga.
In group C, I think they will also find it difficult to finish in third place, and continue the season in the Europa League, something that is realistic but also seems impossible to make happen. Napoli and braga will fight for a place in the runners-up, and madrid will most likely qualify as group winners.
