The debate or investigation into what went wrong will go on for some time. Was it the manager's fault in sticking rigidly to 4-4-2 or the players' fault for some inscrutable reason like incompatibility as personalities? I suspect there is a lot more to tell about this. Were they bored living and training together for 5 or so weeks? Is that relevant? Wouldn't it make them more eager and enthusiastic to be actually playing?
The links below are two representative views from Michael Owen and Roy Keane, both players with World Cup experience:
