The Scot revealed he was "baffled" by
poor form in South Africa. Fabio Capello's team finished second in their group, behind the United States, and were then hammered 4-1 by Germany in the second round.
"That is going to be one of the imponderables - what has really happened and why are they [England] not getting better form," stated Ferguson.
"I watched their games and was baffled by what I saw. Expectation was a big thing. They qualified from a group which you'd have to say was a million to one they wouldn't qualify from. So it was an easy passage into the finals.
England's World Cup dream is over
"Maybe it would have been better if England had been in a tougher [qualifying] group. They'd have earned the right to be one of the favourites and it would have helped that they'd played good teams before they got there."
Ferguson said he had been particularly impressed with
and argued that their winning mentality and the Bundesliga's winter break had helped them through to the semi-finals.
"The history they've got [in Germany] is quite incredible," said Ferguson. "That organised mentality they have, the belief in themselves, it carries them a long way.
"The German mentality is 'we are always in the semi-finals'.
"Plus the fact they get a month's rest in January - it must help. All the England team are playing [in the Premier League] so they're all affected [by the lack of a winter break]."
However, Ferguson is tipping the
- who take on
in Tuesday's first semi-final - to win the World Cup.
He added: "I don't think they have played anywhere near their best form."
