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.
Its first time for Bundesliga teams Union Berlin participants in UEFA Champion League, I know less experienced and have been in difficult group made Union Berlin loss 2 of 2 matches. Union Berlin can' take advantage when playing in their home from Braga opponent and almost difficult chance to qualify knock out round exactly upcoming match against Napoli. Actually, Union Berlin have good games on first opening match, success made Real Madrid scoring goals and need waiting until last minute but they can defend with their consistency performance on last match after losing with Braga.
Not get points yet in last two Champion League matches will make Union Berlin have difficult chance if want qualify to next round, I think in Group C Madrid and Napoli will qualify to knock out round.
