Before I get around to answering
Amit Varma's question, let me just say that England are not going to win it. I'll just let that thought sink in for you England fans. They simply aren't good enough.
A team whose fortunes live and die with a 20 year old, however talented, cannot seriously be considered contenders for the world's biggest prize. Contrast the Rooney situation with Argentina's handling of Leo Messi and Carlos Tevez. Two of the brightest young talents in Argentina were injured before the tournament began (Messi with a hamstring strain and Tevez with an upset stomach), but there was precious little media frenzy regarding their fitness. Argentina's manager Jose Pekerman did a fantastic job of diverting attention away from Messi and Tevez's unavailability for Argentina's opener, choosing instead to talk about what Crespo and Saviola could do for the team. The result was a convincing victory in their opening match against Cote d'Ivoire. Only when Messi and Tevez were fully fit did Pekerman unleash them on a bewildered Serbia & Montenegro. Now you may say that Argentina have far more options up front than England, but that's England's own fault. A quick glance at the players that were left out of the squad by Eriksson tells the story - Darren Bent, Jermain Defoe and Andrew Johnson are all watching the World Cup on television. Instead, of England's four forwards, two are recovering from long-term injuries, another has never even played in the Premiership, and their only fully fit, experienced striker is a 6 ft 7 in beanpole who - let's face it - is well short of being world-class. Compare that to Argentina's forward line - Messi, Tevez, Crespo, Saviola, Rodriguez, Gonzalez, Palacio. Brazil have taken Ronaldinho, Kaka, Ronaldo, Adriano, Fred and Robinho. All top-class players, and all of them have been proven at their respective clubs.
England's central midfield should be a cause for concern. Frightening on paper, insipid on the field. Steven Gerrard and Frank Lampard are world-class box-to-box midfielders for their clubs, but they just cannot play together unless one of them curbs his natural attacking instincts. At club level, both of them play with a defensive midfielder to provide cover for their forays into the opposition third. Gerrard has Momo Sissoko at Liverpool, and Lampard has Makelele at Chelsea. England have no such cover, as their most defensive-minded player is probably Beckham on the right wing. Until England play a holding midfielder behind Lampard and/or Gerrard, they will continue to look lost on the pitch.
Beckham on the right wing - there's an inspired selection. There are at least two right wingers in England who are miles ahead of Beckham and offer far more to the team going forward. I'm talking about Aaron Lennon and Shaun Wright-Phillips. Lennon is in Germany but is a substitute, while Shaun Wright-Phillips has been out of contention ever since he quit professional football for a bench-warming job at Stamford Bridge. If Eriksson absolutely has to play Beckham (and apart from his free kicks I can't see why he should), then his best position would actually be as the aforementioned holding midfielder, behind Gerrard and Lampard.
England's defence is fine - no problems there, unless Sol Campbell gets a game
My next point is regarding England's style of play. In a nutshell, boring and uninspired. A lot of this has to do with the wrong players being on the pitch, and the squad being short of world-class strikers. The major problem, however, is the presence of Peter Crouch. Don't get me wrong - I think Crouch is a very useful player, but he seems to give Beckham and co. the idea that he's better in the air than he is on the ground. It is mind-numbing to see long ball after hopeful long ball punted up towards Crouch, just because he's huge, all the while knowing that if England kept the ball along the ground and showed some creativity, they might just give Crouch and themselves a better chance of scoring. If they continue to play like this, they'll be ripped apart by the likes of Czech Republic, Argentina, Spain and, needless to say, Brazil.
So, a team that depends on a single, half-fit player to create chances, with a lightweight squad, poor team selection and an outdated style of play is one of the favourites to win. This should be fun to watch.
