England Under-20s
Aaron Morris, full-back, Saracens
Talented all-rounder who was a county sprinter and fast bowler. Kicked a penalty from his own half in last year’s final victory
George Perkins, wing, Saracens
His mum was a Welsh international sprinter and his dad played U18 basketball for England. He has also had schoolboy 100m success
Nick Tompkins, centre, Saracens
Captained England at U16 and U17 level and was also involved in last year’s U20 campaign. He was a flanker until the age of 16
Max Clark, centre, Bath
A forceful centre whose mother hails from Bridgend. Attended the same school (Bryanston in Dorset) as fly-half Rory Jennings and the team captain, Charlie Ewels
Howard Packman, wing, Northampton
His father, Frank, played 376 games for the Saints and scored 178 tries. Packman junior has already been selected for England Sevens
Rory Jennings, fly-half, Bath
A product of Salisbury RFC, he has represented Bath at first-team level in the LV Cup. Kicked 13 semi-final points against South Africa
James Mitchell, scrum-half, Sale
Benefiting from the knee injury that ruled out Exeter’s Stuart Townsend from the tournament early on. Learned the game at Lymm RFC
Ellis Genge, prop, Bristol
Strong prop who has represented England from U17 level upwards. His cousin Gregory Streets played basketball for Great Britain
Jack Walker, hooker, Yorkshire Carnegie
Highly rated. Started last year’s final on the bench and has captained England U16s. His dad played for Otley, Batley and Keighley
Paul Hill, prop, Yorkshire Carnegie
Another big unit, he was part of England’s title-winning pack in Auckland 12 months ago. Will be joining Northampton this summer
Will Witty, lock, Newcastle
Has already featured in two Premiership games for the Falcons after joining the academy in 2013. Hails from Malton in North Yorkshire
Charlie Ewels, capt, lock, Bath
A highly-regarded leader with a good deal of ability. Appeared three times for Bath in last season’s Premiership campaign but grew up in Bournemouth
Lewis Ludlam, flanker, Northampton
Suffolk-born forward who was initially released by Northampton before forcing his way back into favour at the Saints academy
Will Owen, flanker, Leicester
Also from East Anglia, the Ipswich-born flanker was introduced to the game at Diss RFC. He is also a keen shooter
James Chisholm, No8, Harlequins
His older brother, Ross, also plays for Harlequins and his father, Peter, was on Everton’s books in the 1970s. Growing up in Haywards Heath in Sussex, he did not play rugby until he was 15 but has made rapid progress since

New Zealand Under-20s
Mitchell Hunt, full-back, Auckland
Having turned 20 on Friday, Hunt is hoping to have something else to celebrate this weekend. He was the starting centre until Otere Black arrived before slotting into full-back. Stepping into the first receiver role from time to time, he provides variety in the backline
Jack Goodhue, wing, Canterbury
The other half of the twin brother combo, Goodhue, like Akira Ioane, has come through Sir Gordon Tietjens’ sevens system. His speed, fitness and tireless work ethic in sevens carries over to the U20 side
Anton Lienert-Brown, centre, Waikato
A late arrival in Italy, Lienert-Brown has played a regular role in the Chiefs’ run to the Super Rugby play-offs this season. Having added plenty of bulk to his frame following the 2014 tournament, Lienert-Brown has moved to another level, mainly thanks to his decision making
Tinoai Faiane, centre, Auckland
Faiane was a bit-part player for New Zealand in 2014 as an 18-year-old but has been one of the stars of the 2015 team. His partnership with Black and Hunt in running the backline has proved lethal. Fast, agile and powerful, making him tough to stop
Tevita Li, wing, North Harbour
Another Super Rugby player for the Blues. It’s hard to believe that Li was lacking in confidence heading to Italy. All that is behind him after grabbing the record for most tries at this level in the semi-final win over France. His improved work rate and defensive effort have led to him improving tenfold on his 2014 performances
Otere Black, fly-half, Manawatu
Another Super Rugby player, Black played two games for the table-topping Hurricanes before flying out late for the world championship. Not flashy but Black leads the team around the park with assurance and accuracy. One of New Zealand’s most accurate goal kickers
Te Toiroa Tahuriorangi, scrum-half, Taranaki
Union and league scouts have been after his signature. Why? He’s been described as a “mini Sonny Bill Williams”
Ricky Riccitelli, prop, Hawke’s Bay
Typically a hooker, Riccitelli has slotted in as prop for the New Zealand side to help form the best pack the country has had at U20 level in the past four years. Like all New Zealand forwards, Riccitelli has good skill on the ball but his work rate is what sets him apart from other props
Liam Polwart, hooker, Auckland
It has not taken long for Polwart to catch the eye of Super Rugby franchises in New Zealand. He played for the Chiefs’ development side in 2015 and could make the move to the full squad for the 2016 season. Still a work in progress at set-piece time but a solid performer in Italy
Atunaisa Moli, capt, prop, Waikato
New Zealand’s captain, Moli, demands huge respect, or mana, from team-mates and coaches. Moli was part of New Zealand’s 2014 squad and was taught a lot in two losing encounters against South Africa that time around. A future All Black
Joshua Goodhue, lock, Canterbury
Playing alongside his twin, Jack, in the New Zealand team, Joshua made his debut for the Canterbury national provincial championship side in 2014, featuring alongside players such as Adam Whitelock. His older brother, Cameron, plays as a flanker for London Welsh
Hamish Dalzell, lock, Canterbury
The cousin of the All Blacks lock Sam Whitelock, Dalzell has many of the same qualities on the rugby field. A proven ball-winner at lineout time, Dalzell is part of the Canterbury rugby academy and could soon be playing alongside his All Black cousin at provincial level
James Blackwell, flanker, Wellington
At first sighting, coaches struggle to name one thing Blackwell does well. The main reason being he does everything exceptionally. One of New Zealand’s most accurate players, he’s also one of their smartest. He is capable of playing lock and is strong in the lineout
Blake Gibson, flanker, Auckland
The question that often comes up in New Zealand is, quite rightly, who will be the next Richie McCaw. Enter, Blake Gibson. With four Super Rugby caps for the Blues already, Gibson has earned high praise for his work ethic and ball-pilfering abilities
Akira Ioane, No8, Auckland
Another from the New Zealand Sevens team, where he was a breakout star in 2014. Now he is carving up the Super Rugby stage
