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.
An international break can't be the reason to say Bayern Munich won this game because of the international break but I think the reason is clear, Bayern Munich got much better and stronger players compared to Union Berlin and a better coach also they invested much more in this season and obviously after these difference the 3-0 result should be very normal for a team like Bayern Munich with the situation they have.
