The match between Bayern and union Berlin was not favourable for the away team that has not lost to anything since the resumption of league matches after the international break, but they lost to Bayern last weekend in a 3:0 defeat against them, thats to say their unbeaten record has been broken and the really need to intensify their effort in other to win future matches.
I think it's also very natural that Union Berlin lost at Bayern Munich because what Union Berlin faced was the best team in the Bundesliga so it wasn't so embarrassing for Union Berlin. After all, Bayern Munich is also trying to maintain itself at the top of the standings after Dortmund briefly took their top position and now Bayern Munich is also still under pressure from Dortmund because the two points are still the same in the standings.
Brusia Dortmund is much more in good form this season and as it stands now they have been unbeaten in most matches the have played so far, they have been so tactical in the recent time and this has earned them somuch success lately so for now they are very strong side and their match with Rb Leipzig this weekend might favour them considering their good form and constant winning in the league.
Brusia Dortmund is also improving its appearance so far because considering they are still in two different competitions and still have a chance to get the title, although I'm not so sure that Brusia Dortmund can get the title in two competitions this season easily. But with the acquisition of temporary points in the Bundesliga that are already the same as Bayern Munich, at least this has provided Brusia Dortmund with the opportunity to fight for the Bundesliga title this season.
