With 8 games to go, the potentially toughest games where Bayern could lose points are:
Dortmund (home) - they're doing pretty bad in the league but can still be dangerous if they show up motivated for their biggest rivals.
Mainz (home) - Mains is currently ranked 3rd.
Leipzig (away) - Leipzig is 5th, they have some dip in performance but showed some signs of improvement in their recent win against Dortmund.
Unless something goes really wrong with the team, I don't see Bayern losing 6 points till the end of the season. If they keep their performance on a consistent level, statistically they're expected to lose 4.94 points before the season comes to an end. And even if Bayern trips, Leverkusen winning all the remaining 8 games is highly unlikely. But, nonetheless, they should keep trying.
