Im sure that union will take the first spot again. Bayern always has a very good performance during the champion league but it has a horrible performance on bundesliga. We have not yet entered into the middle of season. I think that bayern's management can fix it anytime. It seems like you shall not feel worry about that. People understood the main aim from bayern was champion league. Bayern have more chance to win the bundesliga. Union has a consistent performance but i didn't think if it will be last until the season will end.
There will be lots of things happen anytime. people must wait until their teams will give them big surprised at the middle until the end of season.
Positive results in the last few matches of Union make them more confident now.
5 matches with 3 wins and 2 draws as opposed to Wolfsburg which 3 lost 1 draw and 1 win in the last 5 matches.
This is a top two position match with a second bottom position at the moment so Union Berlin's chances are obviously very big in this match.
