England head coach Andy Robinson has no doubts about the self control of Lewis Moody, despite the firebrand flanker getting sent off at Twickenham ten weeks ago.

Leicester forward Moody became the first England player to be sent off in a Test match at Twickenham when he was dismissed for punching during the 40-3 victory over Samoa.

His indiscretion cost him a nine-week ban, and he has only played 39 minutes of rugby - for Tigers against Sale Sharks last Saturday - since his suspension expired.

Robinson is certain Moody will be up for the job when England launch their RBS 6 Nations campaign against reigning champions Wales this weekend.

Moody will pack down at openside flanker in the back row, partnering Joe Worsley and skipper Martin Corry, with Lawrence Dallaglio on replacement duty some 17 months after he retired from international rugby.

Robinson said: ''Lewis has had nine weeks to focus on this game, that is what his training has been about and he has worked very hard. I have no doubt about his self-control.

''I have gone on the record as saying the sending-off was disappointing, and you can never condone a player throwing a punch on the pitch, but in the physical game of rugby it happens.

''Lewis is an outstanding player and I have been in full contact with him for the last nine weeks.''

Robinson has made four changes from the side that accounted for Samoa, with Newcastle centre Jamie Noon returning instead of James Simpson-Daniel, wing Ben Cohen taking over from Tom Voyce, lock Danny Grewcock back for Louis Deacon and Worsley selected instead of an injured Pat Sanderson.

England haven't lost to Wales at Twickenham since 1988, and Robinson has made no secret that Saturday's encounter is all about winning.

''You look at the strength of your bench, and you see what high quality it is,'' added Robinson.

The focus is purely on Wales, and the key for us is to win this game. I think we have picked a starting XV and a 22 that can beat Wales, and for us it is about getting that winning momentum.

''We all know what happened against Wales last year. Having lost 11-9 to a kick in the last five minutes of a poor game, one team went on to win a Grand Slam and generate some momentum and belief, and we stuttered a little bit.

''When you look at a player like Lawrence Dallaglio coming off the bench, then it would be very good for the side with the leadership he would bring.''

With Bath's Olly Barclay ruled out of the midfield equation because of a dislocated thumb, Robinson was always going to go with a combination of Noon and Mike Tindall that served him against New Zealand in November.

Simpson-Daniel, the Teessider who plays for Gloucester, was given his chance against Samoa but was injured before he had a proper chance to show his paces.

Scrum-half Harry Ellis also deservedly holds off the challenge of Matt Dawson, while Bath prop Matt Stevens is rewarded for his club form, with the more experienced Julian White confined to bench duty.

England, especially with home advantage, will go into the game as firm favourites to end Welsh hopes of achieving a second successive Grand Slam at the first hurdle.

The Welsh, as if their Twickenham trip wasn't tough enough already, have lost several key players to injury, while star centre Gavin Henson is still serving a ban.

Robinson has repeated his assertion that England will go into the game as underdogs.

''I firmly believe that Wales are favourites - they are holders of the Six Nations title, Grand Slam and Triple Crown,'' said Robinson.

''They are a talented side, as we saw with many of their players on the Lions tour last summer, and they are favourites for the Six Nations
