Neither did players like Berbatov, Hargreaves, or Carrick, to name a few in recent times. Isn't that policy a bit of a myth at this stage? I mean, f*ck, when's the last time we actually signed a footballer who met that criteria? Ronaldo in 2003, maybe? Hernandez will potentially move for more than we paid for him but I can't think of many others. We'd likely get peanuts for Nani, Anderson, Valencia etc at this stage. Fair enough there's players like DDG, but I'd hope we wouldn't actually think of selling him cause that'd be madness.
Our record at signing youth since Ronaldo & Rooney has been really, really poor, for the most part, and our most successful signings have largely been players who were not youngsters when we got them. We need to sort out our shit midfield and running the risk of signing another Anderson isn't the way to do it. Sir Alex pissed about with the midfield for years and if it takes a Schweinstiger or whomever to solve the issues, at least temporarily, then so be it.
