I think with Bayern is they don't fall to inadequacy they have a plan, a hierachy in the club.
At United so much power was afforded to SAF that as-soon as he steps back and you give a manager like Moyes ultimate power to say sack who you like and he changes everybody... it doesn't work then there's a hangover.
The fallout is still there from that decision, teams like Bayern and especially Spanish sides theres so much politics involved it's completely different, in some ways Manchester United hasn't changed since 1986 (the running of the club) and it does need to be brought up to speed a little bit.
It's great there's ambassadors like Schmeichel, but if you look at the "Legends" of Bayern on the board such as Rummenigge he understands the club from his playing days and understands the needs of the club.
I feel that's missing with United at times, with the changing of managers it needs to change in part. Note how all of this now is happening perhaps without Ancelottis full consent these players were already in negotiations months ago, deals aren't done overnight.
The succession plan is there with or without Pep or the next manager, with United it doesn't feel that way.
