Well, when it comes to financial information, SPORT is actually to be trusted because its parent company is in the finances side and cannot risk printing BS. The sporting information is what's biased. And in fact, when they're not busy campaigning for referee crusades against Barça, As is quite on point too even if it's regarding their rival. As a little fun fact, Sport's main editorial comment comes from a non-Catalan, Emilio Perez de Rosas, while As head honcho Tomas Guasch is an Espanyol fan from Barcelona. As you can see, business is business.
Tevez, I don't think Higuain or Lass make it to next season in Madrid. I wouldn't be surprised to see Higuain wind up at ManCity, because Florentino has been stiffing him all season in his contract talks and now all the hate coming at the kid from every Madrid-leaning media outlet is pretty intense. This is the same president that gave up on Makelele, the glue to the highly succesful early-decade Madrid squads, because of media pressures. Given that Laporta is leaving Barcelona this summer, his and Florentino's non-aggression pact is off and both rivals might resume pursuing each other's players. Toure is known to be unhappy with Barça's brass, and Guardiola is a huge fan of Higuain who also happens to be Messi's closest friend outside of Barcelona. The situation might be too convenient.
I doubt Ribery ends up playing for Madrid either. The only reason this rumor has the wings it has is because Alain Migliaccio, his agent, is a known scumbag who pushes his client around to the highest bidder every summer if he has the chance, and we know who that usually is. It's even worse than Boras, because in Boras' case he makes his money off a cut of his client's money and therefore also vies for the player's best financial interest. In European soccer agents receive a signing bonus when they deliver a player, so the best deal for the agent isn't always the best deal for the athlete. This being said, the talk in sports radio (Spanish, pro-Madrid sports radio at that, not the Catalan media with a Barça bias) is that Sandro Rosell's more than likely arrival as Barcelona's president could sway both Ribery and Cesc towards Camp Nou. Rosell is seen as a guru of sorts. He signed Ronaldinho to Nike, then brought him and Eto'o to Barcelona before falling out with Laporta and leaving his management position. He is known to have excellent relations with both Migliaccio and Darren Dein, Cesc's agent/confidant.
