I'd love Rangnick but it seems he doesn't want to coach anymore, unless it's a huge club like Bayern or Man u?
He wants a project and he wants control over his projects, that's the crux with him. If he's in, he's basically the boss and you do stuff his way or he's off. That's why he's said he's only interested in coaching gigs like his Salzburg days and his latter Leipzig days, being coach and DoF in one person. If he can't have that, he's only available for exec posts like DoF or the like.
