Surprised there's no thread for this yet!
Squads starting to roll in now; today is the final day for announcing them. Wikipedia has them all here.
Ashley Cole being left out of the England squad (and then released by Chelsea) was a bit of a surprise, especially as Gerrard and Lampard are both included. The US left out Landon Donovan, which I can't understand at all; they've possibly the toughest group of the lot and surely need every bit of experience they can draw on (and Donovan's still a decent player). Spain have left out Navas and Negredo from Man City. Falcao has made Colombia's squad, though I don't think he's played since the injury in January.
Colombia have Faryd Mondragon, their goalkeeper from the 1994 World Cup in their current squad; he's 42. He's 4½ years older than the next oldest player, who's his own centre back.
I fancy Germany for this one. I know a lot is made of every South American World Cup being won by a South American team, but I reckon football becoming increasingly globalised has reduced that impact to an extent (Brazil have only four home-based players, for example). Brazil and Argentina should certainly challenge, you'd imagine.
Would like to see something memorable from Messi in this World Cup. But maybe that's being greedy. :)
12th of June is the start.
