1. Borussia Mönchengladbach - Leverkusen: Leverkusen wins
2. Freiburg - Vfb Stuttgart: This is going to end in a goalless draw.
3. Borussia Dortmund - Frankfurt: Dortmund wins
4. Wolfsburg - Bayern Munich: Bayern Munich wins with more than 2 goals margin.
It will be a wrong move to bet against Bayern Munich that they are going to lose or draw at the start of the season. When the season has gone into some game week and the champions league starts, then you can have doubts about teams like Bayern Munich winning. Their league games will be draws or losing because they will be playing too many games by then and the players would be tired.
The first game will have been a very interesting one between Monchengladbach and Leverkusen but over the past two seasons now the club Borussia Monchengladbach have been a shadow of themselves and have had their best players leave. Last season they struggled really hard and without any major signings this summer yet I think they will likely be struggling to get Europe spots. So even though I think the game will be a bit difficult for Leverkusen I will predict a narrow win for them.
As for Bayern Munich and Wolfsburg I think that game is as tricky as that of Leverkusen. Bayern Munich in some matches before have struggled against the wolves and as the first match I think the wolves will be coming out strong in this game. But still a narrow win for the record champions.
Dortmund and Frankfurt is the most trickiest match I see here, both teams out of the top four last season although Dortmund had a better European campaign and right now have a better squad overall coupled with the fact that they have a new coach looking to make a statement I predict their win
