Manchester United defender Rio Ferdinand has slammed England's pre-World Cup form.

There are only 11 days until England start their World Cup bid against USA.

But Ferdinand believes there is still time to work on the problem areas after their scratchy friendly win over Japan.

He said: "In the first half we were a bit too slow. There wasn't much thought process in the way we played. We are getting to the point where we are working it out and sorting it ourselves. We went on to look quite dangerous in the second half.

"I thought the subs made a big impact in the second half.

"Going into a tournament you need players who are going to come off the bench and make a difference. To come back from a goal down against a good Japanese side was good.

"They didn't have many chances on goal apart from the set piece. That is a good sign. But there is a lot of hard work in front of us.

"Japan are a good side. They have always got good imagination. They work hard and they have very good players."
