Lawrence Dallaglio has offered an explanation for England's roller-coaster form which was as bizarre as their 40-5 victory against Italy at Twickenham.

England coach Clive Woodward, insists Dallaglio, is spoiled for choice - with too many players playing well at the same time.

With the RBS 6 Nations Championship having been squeezed into two months, there has been an inevitable spate of injuries and changes in personnel and positions. That, according to Dallaglio, is one of the reasons for the uncertainty in England's error-strewn game.

"There are an enormous number of people playing well in lots of positions," said Dallaglio after Sunday's wide-margin win.

"Because of the truncated format of the championship, it means Clive Woodward has already looked at a lot of players.

"From a coach's point of view that has raised a lot of questions. It is difficult to know what the best team is.

"We haven't hit our rhythm yet and we certainly can't be accused of peaking too early."

There was some validity in Dallaglio's observations, considering England went into the Italy game having been forced to make six changes because of injury and with a new captain in Jonny Wilkinson.

Then they were required to use all seven replacements yesterday because of more injuries, including a slight shoulder problem for Wilkinson and a serious leg injury for his fly-half replacement Charlie Hodgson.

The one undeniable positive of a triumph which kept England on course for a Grand Slam decider against Ireland at the end of this month, however, was the spectacular early form of full-back Josh Lewsey.

The Wasps player scored two tries, with hooker Steve Thompson and wing James Simpson-Daniel grabbing their first touchdowns in a white shirt while Mike Tindall and Dan Luger added the others. It was the second of Lewsey's, a spectacular 60 metres solo effort, which left team-mate Dallaglio purring.

"Josh is a strong player and offers something different," said Dallaglio.

"He is not Jason Robinson but he made a powerful case for himself, and I'm sure Clive Woodward noticed that."

It was enough to earn Lewsey the man of the match award, although the full-back revealed the disappointment in the England changing room after the home side had scored five of their six tries in the first 21 minutes, only to labour disappointingly for the next hour.

"It was good for the first 20 minutes," said Lewsey.

"It was a very sober dressing room at the end because it was a frustrating game. We made so many unforced errors - but on the positive side we have won three out of three and scored 40 points against a very good Italian team.

"We went out to attack and attack and get back to what this team is best at. By doing that you tend to enjoy your rugby. The guys I was playing with can rip teams apart.

"I just think a few nerves crept in. It was just one of those days where the errors crept in and spoiled the rhythm of the game."

Lewsey admitted, however, that after the first 20 minutes in which he scored that phenomenal touchdown he was beginning to think international rugby was ridiculously easy.

"It was bizarre," he said.

"I scored my second try and thought this international lark is all quite easy really. The boys were flying then and putting me into holes.

"When you've got the likes of Simpson-Daniel and Luger and Greenwood around you people are so wary of them that things tend to open up.

"We were disappointed to let in a try but with the amount of ball that they had we defended as a team very well. We worked very hard.

"If the ball had gone to hand for the last 60 minutes we would have ripped that team apart. That's a very good Italian team.

"It's an inclination of the ambition of this side to be the best team in the world that we come off the field after putting 40 points on Italy and everyone has got their heads down. When it does click, though, you can see the potential that is there."
