Really? Cause I can't see anything that remotely suggest that. United had been taken for a ride by agents for the past 7 years. If its true that Ole has more salary then Klopp (previous contract) then we can say that even our former players are taking us for a ride as well cause there's no way that a manager who had failed at any level that is not amateur level should be paid as much. We've got one of the highest salary bills in Europe and a mid table level squad to show for it.
As said, most clubs have a history of raising into position people of their own. That's because they have a solid structure which allows them to do so. A former player is introduced to an experienced set up were he's shown the ropes up until he doesn't need help anymore and in turn he becomes the 'veteran'. Therefore the cycle goes on and on until, somehow along the line it breaks and it needs to be built again. For example when Juventus had to do a clean up because of Calciopoli, their only option was to go for outside talent. That outside talent translated into the very experienced Marotta whose got a CV as long as my arm. Marotta brought in Paratici from Sampdoria. Then once the structure was built, people 'closer' to home were brought in like for example Conte.
United need to build a solid structure lead by experienced people on top of their game. Then once that is in place then sure we can start adding people of our own and hope that they would learn and one they become protagonists in our rebuilt. Unfortunately what we seem to have are a bunch of people who are learning on the job (Woodward, Ole, Carrick, Mckenna and possibly Cruyff) with the assistance of the occasional dinosaur (Phelan)
