We conclude our series by looking at the four teams in Pool C at the World Rugby U20 Championship 2015, which features New Zealand, Ireland, Argentina and Scotland.
Seeding for 2015: 3
Best finish: Champions (2008, 2009, 2010, 2011)
Worst finish: Fourth (2013)
U20 match record: Played 35 / Won 29 / Lost 6
U20 points/tries scored: 1,496 / 206
U20 graduates: 21
Most capped U20 graduate: Sam Whitelock (62 tests)
Did you know...? New Zealand won their first 21 matches in the World Rugby U20 Championship, a run ended by Wales with a 9-6 victory in muddy conditions in the 2012 pool stages in South Africa.
Coach: Scott Robertson
Captain: Atunaisa Moli
One to watch: Otere Black
A member of the Hurricanes wider training squad in 2015, Black has been thrust into the spotlight recently after an injury to All Black and 2011 U20 Championship winner Beauden Barrett left a void to fill. The 20-year-old fly-half stepped up and enjoyed an impressive starting debut against the Blues to show why coach Scott Robertson labelled him as the man to lead the under-20s backline. An accurate goal-kicker, Black is also a keen student of the game.
Seeding for 2015: 4
Best finish: Fourth (2014)
Worst finish: Ninth (2008, 2010)
U20 match record: Played 35 / Won 16 / Lost 19
U20 points/tries scored: 831 / 89
U20 graduates: 19
Most capped U20 graduate: Conor Murray (37 tests – 35 Ireland, 2 Lions)
Did you know...? In 2010, Ireland captain Rhys Ruddock became the only player to be called away from a U20 Championship to join up with the senior team. He duly made his debut against the Wallabies.
Coach: Nigel Carolan
Captain: Nick McCarthy
One to watch: Garry Ringrose
Long talked about as a player capable of filling the 13 jersey vacated by Brian O’Driscoll, the 20-year-old has already trained with Joe Schmidt’s national squad and played for Leinster A this season. A lovely straight runner with great peripheral vision to spot a gap in defences, Ringrose was a key figure in Ireland’s run to a first U20 Championship semi-final in 2014 and was nominated for the World Rugby Junior Player of the Year accolade. The outside centre is also an accomplished goal-kicker and with the loss of fly-half Ross Byrne, his experience will be invaluable to Ireland’s hopes of success in Italy.
Seeding for 2015: 9
Best finish: Fourth (2012)
Worst finish: 11th (2009)
U20 match record: Played 35 / Won 17 / Lost 18
U20 points/tries scored: 702 / 77
U20 graduates: 53
Most capped U20 graduate: Martín Landajo (39 tests)
Did you know...? Argentina have seen the most players graduate from the U20 Championship to the test arena with 53, including Nicolás Sánchez, Martín Landajo and Pablo Matera.
Coaches: Nicolás Fernández Lobbe
Captain: Bautista Ezcurra
One to watch: Bautista Ezcurra
Light on his feet and with a great pass, the young centre is regarded as the complete player and a Pumas star of the future. He has already played for the Pampas XV, against the touring USA Select side earlier this year. The 20-year-old, who plays for the Hindu club, returns for his second U20 Championship with the added responsibility of the captaincy. His older brother Felipe captained Los Pumitas two years ago and has already made that step to test rugby.
Seeding for 2015: 10
Best finish: Ninth (2009, 2012)
Worst finish: 10th (2008, 2010, 2011, 2013, 2014)
U20 match record: Played 35 / Won 13 / Lost 22
U20 points/tries scored: 708 / 95
U20 graduates: 28
Most capped U20 graduate: Richie Gray (45 tests – 44 Scotland, 1 Lions)
Did you know...? Scotland’s Jamie Farndale played in three U20 Championships and is one of four players to have scored a record 10 tries in their time in the event.
Coach: Sean Lineen
Captain: Jamie Ritchie
One to watch: Zander Fagerson
The young prop may be eligible to play again in the 2016 edition, but he has already established himself in the Scotland under-20 front row and was an ever-present in their much-improved Six Nations campaign in 2014. An impressive display in the set pieces against Italy saw him named man of the match and that physicality will be important in a tough pool. The 19-year-old has eight games with Glasgow Warriors in the PRO12 under his belt.
