Fly half Adam Greendale (Leeds Carnegie) and lock Graham Kitchener (Worcester Warriors) come into the starting line-up with another second row forward, James Cannon (Northampton Saints), on the bench.

Saracens wing Noah Cato has led the way with five tries in the first four wins over Wales (28-15), Italy (22-3), France (24-6) and Scotland (41-15).

And former Bath and England lock Redman is emphasising the messages that have got England this far as they try to finish the job against last season’s Under 20 Grand Slam winners.

“So far our preparation has gone as well and we know we face a big task against the current champions – so we’re expecting a huge game,” said Redman.

“Our messages are the same as they’ve been for all our games – about tempo, about physicality, and about decision making.

“Of course we’ve talked about what’s at stake but the most important thing is to play the way we want to play and the rest will take care of itself.”

Greendale, 19, takes over at fly half from Rob Miller, who has been recalled by his club Newcastle Falcons to join their Guinness Premiership squad.

Kitchener, an 18 year-old studying for A Levels at Adams GS in Newport, Shropshire, replaces suspended Saracens lock Ben Thomas and Nottingham University history student James Cannon is on the bench for the first time at this level.

“Adam Greendale, Graham Kitchener and James Cannon have come into the squad and they have looked good in training,” said Redman.

“They all have the opportunity to express themselves and we’re looking forward to seeing what they have to offer in leading the way rather than following.”

England are the only unbeaten side in the championship and the two sides with a won three, lost one record – Wales and France – meet earlier on Friday night at Rodney Parade in South Wales.
