England v Fiji: Stuart Lancaster challenges his team to aim for cleap sweep in autumn internationals The back three unit has only 17 caps while the back row, with captain Chris Robshaw on the flank, contains only 11 caps. Eleven of the starting XV have 13 caps or fewer. Lancaster is adamant that he has not gambled but does acknowledge that the high turnover of personnel during his time in charge is coming to an end. "It's not a risk picking these players because they are the form players," said Lancaster. There is no definitive thing about being too young or too old as far as I'm concerned. It's an intuitive thing. There needed to be a period of change. But if we're sat here in 2014 asking questions about our inexperienced side, I'd be very worried. We had to start somewhere. The All Blacks don't seem to go through this period of renewal. It's a drip-feed. That is where we should be from now on. I don't see England in the next eight to 12 years going through the same change we have had to this time. This selection is even more callow than the Calcutta Cup side, with seven new caps, that Lancaster picked in his very first game, though the most inexperienced team they have had to date had just 61 caps, in 1984 against Australia. By point of comparison, the average caps total of the winning side over the last four World Cups is 660. England are some way from that but Lancaster points out that the new generation are better equipped to cope with the demands of top-flight rugby than their predecessors. "The 20-21 year-olds are a different breed," said Lancaster. They are far more technically prepared, far more physically prepared and are mentally robust as well. There is a sense of freshness and vitality about England that needs to translate into productive action on the field. Fly-half Toby Flood is the elder statesman of the side with 50 caps. "That no-fear mentality that Stuart has managed to create has helped the guys to go out and express themselves," said Flood. There is such youthful exuberance there, such vigour in the side, that they want to play. Lancaster was at pains to stress that his young charges needed to learn first and foremost about the virtues of "game management" and of "playing for all four quarters." For all their fitful promise in certain matches, England have not delivered an all-encompassing performance, notable as their win in Paris, their thumping home victory over Ireland and the 14-14 draw in the third Test in South Africa were. Injury and suspension have forced Lancaster's hand to a large extent for this match but he expressed his faith in Tom Youngs and defended his preference for Alex Goode over Mike Brown at full-back. "Tom has shown his mental resilience in making the switch from centre to hooker while Alex brings an extra footballing dimension and allows us to move the ball in certain ways," he said. England rejected the notion that this match would be a mere loosener ahead of the duel against the southern hemisphere superpowers. "The Fiji centres are the form players in the Premiership and can cause terror in defences," said Lancaster. If we start thinking we can score 50 points we'll be in trouble. We've got to control their desire to play as well as their desire to smash us. It's about concentrating on our game, about playing with pride and working hard for each other and for the shirt. It is 10 years since England managed a clean sweep in an autumn series. The new broom will have to be at its bristling best to replicate that.
