As long as Bayern still cannot be stopped by any club in the Bundesliga,
They got a few times some luck that they not lost some games against other teams , specially the last game against Leverkusen they was very lucky.
On top of that there are mayn teams that can be the one where they can losing , the smaller teams are the most one to fear.
And i would be not surprised if one of that Teams can catch a point from Bayern Munich or even more when you dont expect it.
Since a few seasons actually unexpected defeats from even unexpected clubs always happen for Bayern so indeed in the remaining matches at this time they are still quite able to lose but even so, regardless of whether it is called luck or not, the fact is that until now there is still no one who can beat Bayern apart from Mainz who managed to get a narrow 2-1 victory last December.
Obviously this is a situation that although many clubs expected especially for Leverkusen but it is very difficult for other clubs at this time to bring Leverkusen to their knees in a match in the bundesliga so in the end although there is still a possibility of losing but at this time the possibility is small even we may not be able to expect much other than an unexpected defeat.
But for the last few matches at the moment their performance is actually not too good even though they always manage to get 3 points but there are several things including individual player mistakes more often so this could be maximized by other clubs later.
