I recall at the time we appointed him, that people suggested Ramos wasn't the reason Seville won 5 cups under him, it was the team behind him at Seville, IE DoF, scouts etc.
That was the model Levy desperately seemed to want anyway, a coach that could be changed every 2-3 years but a backroom team that stayed and kept the consistency going.
He has pretty much said this publicly as well. Although I can't find anything to prove it, he's definitely said there is a trend abroad whereby manages come and go within 2 years but staff remain the same. And teams succeed that way.
Yeah he's been on about it since 2003. We were also one of the first clubs to bring in a sporting director, in the european model.
People think Levy is a control freak but by evidence he's been trying to hand off the footballing side the whole time - it just doesn't seem like we've manage to hire anyone useful at it beyond Collini, and anyone decent hasn't really had any patience or reality with how the club has had to organically manage its own funding, rather than the Chelsea model of financial absurdity that crept it. Then, we had both Redknapp and Poch (arguably our two most successful PL managers in terms of league performance and finishes) outright throw a complete wobbly about working under a sporting director.
We could probably do much much worse than getting a Monchi type of guy in to build a squad and culture and just having a half decent head coach to pick the team and tactics and knows their limits.
