The worst part about that article are words like "considering" and "impressed" like they are still fucking pondering if keeping a world class manager is a good idea and that they are impressed or surprised in the manner in which he's going about trying to keep this club up.
There isn't another answer here, the solution is hire Rafa long-term, give him whatever he wants, and let him rebuild the club. He says he wants X staff or this rebuilt or that scout or etc. they go and get it fucking done.
