Mike Catt views New Zealand All Blacks as blueprint for England's plan of attack in autumn Tests Vunipola has Tongan genes, a Pacific Islander's deep-rooted desire to put the ball through the hands rather than applying boot to it. Youngs, the older brother of scrum-half Ben, is a converted centre, persuaded to move to the forwards by Springboks coach Heyneke Meyer when he was at Leicester three years ago. "Tom was built like a brick outhouse, had a hell of a good attitude and could carry ball," said England forwards coach Graham Rowntree, who coached the Youngs brothers at the Leicester Academy and admitted that he had never expected to see Tom switch to hooker. The rise of 21-year-old Vunipola has been remarkable. Once he got his lifestyle in order - his appetite for the game only matched by his appetite for breakfast, lunch and dinner - his rise was swift. He gets his chance because of injury to Alex Corbisiero but he has leapfrogged more established props such as Bath's Nathan Catt and Matt Mullan, of Worcester. Vunipola only broke through to the starting ranks at Saracens two months ago and is now on course to fill one of the replacement slots against two of the most formidable packs in world rugby, the All Blacks and Springboks. "I've been watching this young man through the age grades [England under-18s and 20s] and I've been looking for a fault in his game and I can't find one," said Rowntree. He's dynamic in the loose but he also respects the hard yards and loves the scrum. He's got his priorities right in that regard. You can't ignore his form. There is a step up but that step is getting smaller. Of course, there will be a question mark about whether he's good enough at international level. I had reservations about Joe Marler and Corbisiero and they've both proved their worth. I have no doubt Mako will make his name this autumn. Youngs, 25, has served his time at Leicester, understudying George Chuter before getting the starting nod this season. His game is not without flaws but, as he showed for the England midweek side in South Africa in June, there is a restless energy about him. His line-out throwing needs refining but has already built a reputation as a ferocious scrummager. "The throwing will always be a work-on for any hooker," said Rowntree. Like his brother, he's got an exceptional work ethic. In two other changes to the Elite Player Squad, Harlequins wing Ugo Monye returns while Wasps" back-rower, James Haskell, steps up for injured players Ben Foden and Tom Croft. Monye, 29, is back to the sort of form that made him such a star on the 2009 Lions tour to South Africa. He has been plagued by injury in recent years and also appeared to lose his edge. As Harlequins have prospered so too has Monye, who has eclipsed the likes of David Strettle to force his way right back into the reckoning for his first Test start since 2010. "Ugo is hungry to get back out there and prove his worth," said backs coach Andy Farrell. There was no real consideration given to the claims of the French-based players, such as the Armitage brothers, England reiterating their policy that they would only come into the frame if there were "exceptional circumstances', notably a serious run of injuries. The same would apply to in-form Harlequins No 8 Nick Easter. Coach Stuart Lancaster was not present on Thursday because of personal family reasons. However, he will be there to welcome the squad as they check in on Sunday night for a five-day camp at the National Football Centre at St George's Park in Burton. Lancaster intends to set the tone for what lies ahead much as he did prior to the Six Nations Championship when England gathered at a junior rugby club in Leeds. As was the case then, motivational speakers will address the group. England open the QBE series against Fiji at Twickenham on Nov 10 with Australia, South Africa and New Zealand to follow.
