The former England skipper has questioned the jaded team spirit and tactics within the England camp during the World Cup finals.
Shearer said: "No one likes kicking a man when he is down but I have to admit that Fabio Capello has left me feeling utterly dejected.
"This is the worst thing you can say about any football manager, yet it needs saying - it looked to me as if the England players did not want to play for him.
"There was something fundamentally wrong inside that camp and only those who were there know the real problems and can tell the truth about what went on.
"From the outside, though, it looked as if the squad were locked away in a boot camp and let out only on match days."
