ENGLAND
1 MAKO VUNIPOLA: A force of nature and nothing much has changed since, except his scrummaging is better. Two Lions tours and 50 England caps.
2 MIKEY HEYWOOD: Dynamic and quick and there are still those at Saints who will tell you he is a better hooker than Dylan Hartley.
3 HENRY THOMAS: Big athletic prop, made an immediate impact with Sale and then Bath before injury began to bite. Could yet add to his seven caps.
4 JOE LAUNCHBURY: Solid presence at lock, Launchbury had just joined Wasps after Quins strangely let him go. 53 England caps and counting.
5 CHARLIE MATTHEWS: Rangy athletic lock alongside the solid Launchbury, promised big things at Quins before stalling. Now re-joins Launchbury at Wasps.
6 SAM JONES: Gifted and versatile Wasps back rower who was promising great things before his career-ending injury learning judo at an England camp.
7 MATT KVESIC: For some reason people think he's older! Fitted in well into this side but England senior coaches not convinced. Now with Exeter. 3 England caps.
8 ALEX GRAY (CAPT): Big things expected from the athletic No.8 but has turned to American Football and signed a Reserve Contract with Atlanta Falcons.
9 CHRIS COOK: Tight call between him and Dan Robson. Still going strong at Bath but has encountered some injuries on the way.
10 GEORGE FORD: Smooth midfield link with his old schoolboy mate and England U18 colleague Owen Farrell. Now has 47 caps.
11 CHRISTIAN WADE: A threat all tournament and still the most dangerous back in England although various national coaches think otherwise. One cap.
12 OWEN FARRELL: At inside centre, just like he tends to be with England and the Lions. Stand out then and now. 60 England caps, two Lions tours.
13 ELLIOT DALY: Brilliant versatile back probably playing his best position. Toured with 2017 Lions and winner of 20 England caps.
14 ANDY SHORT: Quick powerful wing with Worcester and Bristol who was forced to retire aged 26 with a hip problem. Training as a surveyor.
15 BEN RANSOM: Pacey utility back who made 44 appearances for Saracens before joining Bedford Blues and then London Irish.
BENCH:
Rob Buchanan: Powerful hooker who is still doing his stuff for Quins Will Collier: Strong scrummager. 2 caps in Argentina last summer. No stranger to injury.
Sam Twoomey: Yet another Quins forward and another to suffer injuries.
Matt Everard: Spells with Tigers and Wasps before joining Nottingham. Now retired and coaching.
Dan Robson: Made his mark at Gloucester and now at Wasps, excelling in tandem with Danny Cipriani at half-back.

Marland Yarde: Developed quickly, try scorer with London Irish, Quins and Sale. 13 England caps.
1 SLOMINA SAKALIA: Hasn't made a huge impact at senior level, plays for the Bay of Plenty in the ITM Cup and spent one season in the Chiefs Super Rugby squad.

4 STEVEN LATUA: Former Samoa U20 cap was poached by New Zealand U20 for this tournament. Won 16 caps in back row, now playing for Bristol.
5 BRODIE RETALLICK: Looked a man among boys at this level and quickly developed into the world's top lock. World Cup winner in 2015 and 68 caps already.
6 BRAD SHIELDS: Rangy back row man, has become the Hurricanes captain and recently opted for England courtesy of his two English parents.
7 SAM CANE: Lived in the shadow of Richie McCaw for a while but now an AB regular at openside and tipped as a future captain.
