What he said.
Obviously we are run as a business, so we should sign a blend of young players with potential (e.g. Ronaldo, Nani, Anderson) who can help build a squad as good as Chelsea's, without needing to match their mentalist spending. Then you combine these "potential greats" with a nucleus of world-class stars who you will hope to hold onto until their best years are over, irrespective of their re-sale value (e.g. Ferdinand, Neville, Evra, Vidic and, oh yes, Berbatov)
I know it's a harsh insult but I can't help thinking that people who obsess about re-sale value (especially looking to make a profit on a
40m transfer!) must be spending a wee bit too much time playing a certain computer-based football manager simulation
