Well,these are some..formations.
Now,let's be serious.
Ancelotti has now picked up domestic titles in his native Italy, England, France, Spain and Germany. Although a versatile coach,he has nonetheless built most of those successful teams - AC Milan, Chelsea, Paris Saint-Germain and Real Madrid - on a 4-2-3-1 formation.
Let's watch this:
Bayern's line up in 2016/17, based on minutes played and average positions.

Having won the league 15 points clear of nearest challengers Leipzig, it is safe to assume that Ancelotti will stick to the old adage of "don't fix something if it isn't broken," at least in terms of his formation.
Further forward, Müller could find himself under increasing pressure from Coman.He suffered injuries to his ankle and then knee which kept him out of contention for much of this term. His four goals and six assists in 2015/16 were testament to his talent.Let's not forget that Ancelotti gave him his PSG debut in 2013 when he was just 16 years, eight months and four days of age.
About my man,Tolisso,Anchelotti said : "I think that Tolisso also has a good profile to replace a player like Alonso." I cannot imagine breaking the club record for someone,and putting him on the bench.So,according to Carlo,he's going to put Corentin in Alonso's place.
If i had to bet on how Bayern is going to look in 2017/18 i'm all in for 4-2-3-1.

I'm sure it's going to be a lot of variations on defence.The only thing i'm sure for-when Hummels is fit,he's starting.
Also,for me Ribery is no more a starter.No matter how,we should develop quick Coman,because he's going to be a 100 % starter after Robbery era,he should be ready for that.
Yeah,i'm not either fan of the Müller on the bench but..We need our left wing to do some damage.(Müller,depending on the opponent) is going to start some matches.
