LVG and AVB together. That sounds like a recipe for either bliss or catastrophe.
LVG is an awesome football man in many ways, but by all accounts his interpersonal and political skills leave a lot to be desired and he falls out with people hard. Very head strong, opinionated and abrasive (at least, away from the dressing room, where he is clearly a good motivator). But in the boardroom and around the politics of a club, he can be a temperamental influence.
Considering that AVB's problems at Chelsea were along the same lines - poor communication, too abrasive and inflexible - if those two don't get along, the situation would very, very soon become intolerable.
On the other hand, that's a lot of combined talent there that if they click could do really incredibly well over 4 or 5 years.
