it's the, let's call it "emotional part" that gets sold out i don't like at all. benzema, the so called french ronaldo, having the same amount of fans attending his presentation as raul albiol says a lot. madridistas are fed up with foreigners unless they are amongst the best of the world like kaká or cristiano. to see the emontional reaction of the bernabeu with regards to granero & negredo is priceless IMO. i certainly would not sell out that kind of ilusion created by canteranos & sure by spaniards like david villa, xabi alonso etc... as well, for 18 - 20m € in negredos case, 5m € diffrence in xabi alonsos case, 5-8m € diffrence in david villas case (hypothetically, at a time when they were willed to sell) etc...these numbers, for a club like madrid are peanuts compared to the ilusion & emotion these players generate.
if players like david villa, xabi alonso & co want to join madrid, it must not fail due to some 5-10m € difference in the end.
