I think it will become a tradition in the Bundesliga, and by that, I mean the regular league title contenders, like Borussia Dortmund & RB Leipzig. RB Leipzig is Bayern Munich's first opponent, we'll see what they can do in today's match, I think the usual result will happen, Bayern Munich win the match.
Without doubt, Bayern Munich stand a better chance to win today's opening game against RB Leipzig. Bayern Munich is the defending champions and would be playing at home too. Bayern dominance in the Bundesliga is not likely to be threatened not by Leipzig who finished last season in a very disappointing position. Leipzig with a new coach might want to impress their fans but I don't think Kompany men will give them a chance to do that. I don't know what the final scoreline would be but I expect both teams to score a goal.
It would be quite embarrassing if Bayern lost. Just look at this.

Their odds are below 1.50, which means Bayern has a nearly 90% chance of winning, the bookmakers are very confident in Bayern, especially since they're the hosts here. I'm quite optimistic they can get all three points but betting on them to win outright isn't very appealing, the best bet is a handicap bet; I'm confident there will be plenty of goals in this match.
