It's not about having a player like Valencia - he's no more than a good player - it's about having 4 or 5 like him to pick from over the course of a long, hard season.
Fergie doesn't have it bad further back either, does he? A £20M goalkeeper, Ferdinand, Evans, Jones, Smalling, Evra, the Brazilian twins, Carrick, Anderson, Cleverly, Scholes - again, there are few in the way of amazing players, but lots and lots of good, solid, experienced players - that's what wins you League titles.
