We conclude our series by looking at the four teams in Pool C at the World Rugby U20 Championship 2017, which features Argentina, former champions South Africa, France and hosts Georgia.
Seeding for 2017: 3
Best finish: Third (2016)
Worst finish: 11th (2009)
U20 match record: Played 45 / Won 23 / Lost 22
U20 points/tries scored: 975 / 108
U20 graduates: 57
Most capped U20 graduate: Martín Landajo (65 tests)
Did you know...? Argentina have seen the most players graduate from the U20 Championship to the test arena, including Nicolás Sánchez, Martín Landajo and Tomás Cubelli who have all reached 50 tests for Los Pumas
Coach: Gastón Conde
Captain: Tomás Malanos
One to watch: Marcos Kremer
A towering presence who can play either second-row or flanker, Kremer was one of the stand-out players last year as Argentina achieved their best-ever finish of third, beating South Africa twice in the process. He had already played for the Argentina XV in the Americas Rugby Championship by that point and his test debut followed against world champions New Zealand in the Rugby Championship last September. With Super experience with Los Jagauares and national coach Daniel Hourcade a big fan, Kremer is certainly a player in demand and was only drafted into the U20 squad at the last minute due to injuries.
Seeding for 2017: 4
Best finish: Champions (2012)
Worst finish: Fifth (2011)
U20 Championship match record: Played 45 / Won 33 / Lost 11
U20 Championship points/tries scored: 1,745 / 236
U20 graduates: 24
Most capped U20 graduate: Pat Lambie (56 tests)
Did you know...? Handré Pollard endured a whirlwind eight days in June 2014 as he went from the heartbreak of losing the U20 Championship final 21-20 to England and being named World Rugby Junior Player of the Year to the elation of making his Springbok debut against Scotland.
Coach: Chean Roux
Captain: Ernst van Rhyn
One to watch: Curwin Bosch
A mercurial talent who many were calling to be involved with the Springboks for the series with France next month, but Allister Coetzee's loss is most definitely Chean Roux and the Junior Springboks' gain. Bosch was one of the stand-out players in Manchester last year when playing mostly from full-back, but is equally comfortable at fly-half. A player in the mould of former U20 captain Handré Pollard in that he is as comfortable with the ball in hand as he is kicking for territory or the posts, Bosch has made the step up to Super Rugby this year with the Sharks with ease and been one of the shining lights in the South African teams.
Seeding for 2017: 9
Best finish: Fourth (2011, 2015)
Worst finish: Ninth (2016)
U20 Championship match record: Played 45 / Won 29 / Lost 16
U20 Championship points/tries scored: 1,224 / 152
U20 graduates: 40
Most capped U20 graduates: Yoann Maestri (56 tests)
Did you know...? Pierre Bernard of France holds the record for the most points scored in a single U20 Championship match with 33 against Wales in the fifth-place play-off in 2009.
Coach: Philippe Boher
Captain: Florian Verhaeghe
One to watch: Romain Ntamack
The fly-half only turned 18 earlier this month, but appears to be blessed with the same talent his father, Les Bleues and Toulouse legend Emile, possessed. He was thrust into the spotlight for his U20 debut after Les Bleuets lost heavily to England in the opening round of the Six Nations in February, but performed with a maturity beyond his years and retained the No.10 jersey for the rest of the Championship. He provides a touch of x-factor and is able to put team-mates through holes or ghost through defences himself. His kicking percentage is one perhaps thing that he needs to work on, but that consistency will come as he matures and France will want to nurture his unquestionable talent.
Seeding for 2017: 10
Best finish: 10th (2016)
Worst finish: 10th (2016)
U20 Championship match record: Played 5 / Won 1 / Lost 4
U20 Championship points/tries scored: 58 / 7
U20 graduates: 34 (three from Championship and 31 from Trophy)
Most capped U20 graduate: Lasha Khmaladze (53 tests)
Did you know...? Vasil Lobzhanidze captained Georgia on their U20 Championship debut in 2016, eight months after the scrum-half became the youngest player in Rugby World Cup history.
Coach: Ilia Maisuradze
Captain: Ilia Spanderashvili
One to watch: Gela Aprasidze
Georgia are blessed with some talented young scrum-halves and while the name Vasil Lobzhanidze is known around the world as the youngest player in Rugby World Cup history, Aprasidze is rated just as highly by Lelos coach Milton Haig and the two will be battling each other for the nine jersey for years to come. This will be Aprasidze's second U20 Championship and he could play a third as he doesn't turn 20 until January. Capable of playing fly-half as well, Aprasidze made his test debut in the Rugby Europe Championship earlier this year and that experience will be vital to the Junior Lelos' hopes on home soil over the next three weeks.
