Borussia M'gladbach won the last game against Schalke 2-0 and still remain one of the best home strongest team in the Bundesliga.
Hertha played DFB Pokal Cup mid week against Bayern Munchen which ended 2-2 and went to extra time to loose 3-2, this will make things more worst for Hertha outfit playing against M'glabach because in the extra time against Bayern was Hertha strength at zero level, that contributed on them conceding the 3 goal.
Strength issue will play a big role in Hertha's game against Monchengladbach, and Monchengladbach will capitalise in that advantage to go for many goals... In the last 28 games they scored 65 goals, Its about 2.32 goals per match.
Monchengladbach has a winning marging since last 6 months 17 from 28 game won. 9 games from 10 games at home and just only one game lost at home.
To avoid much risk, i go for team 1 to score over 1.5 goals ! GOOD LUCK!
