I would imagine that Rafa's 'job' is to do what AVB failed to do, shed the old guard and that's he has been told it directly. I imagine the board see the team is broke and why fix it when a shiny new one would be far better than one using old parts and superglue? Maybe someone holds that old team in high regard and are unwilling to part with it cracks an all as it has huge sentimental value, so what you have to do is push it off the shelf and and smash it completely then turn around and say, ah never mind, I know you loved that old team but we can't fix it now it's beyond repair, everyone would agree best to get a new one eh. Rafa is the one pushing, he knows it, it is his job, he gets a nice wad of money, another line on his CV and a thank you very much.
