Since having the honour of captaining the U18 side against Wales in 2008, loose-head prop Joe Marler has developed into one of England's most reliable front-row forwards.
He stepped up to make his England Saxons debut against Italy A in January 2011 and went on to win his first three senior England caps against South Africa in Durban, Johannesburg and Port Elizabeth during 2012's summer tour.
Joe played in 14 consecutive Test matches before missing the final game against Italy in the 2014 NatWest 6 Nations Championship to be with his partner Daisy in readiness for the birth of their first son Jasper.
He then started all three Tests in New Zealand before playing in all four autumn internationals and every Six Nations match in 2015, so building another sequence of 12 Tests before being rested for the opening Rugby World Cup warm-up game against France.
He started in England's first three matches of the tournament itself and was a replacement against Uruguay.
By the time he made 42nd international appearance against France in March 2016 he had missed only four matches since his debut on the way to becoming a Grand Slam winner.
He withdrew from the subsequent summer tour of Australia and took a break from the game before leading out England for his 50th cap in their stunning victory over Scotland in March 2017.
Three months later, Joe was part of the British & Irish Lions squad for their tour of New Zealand, started in their first match against the Provincial Barbarians at Whangarei and was a regular for the Lions in their midweek games.
Joe joined the Harlequins Academy in June 2008 and spent the ensuing season on loan to Worthing before figuring on a similar basis for Esher.
He first played for Quins' A team against Wasps before making his senior debut for the club against Newcastle Falcons in November 2009.
He was appointed as Harlequins captain for the 2014/15 season, and to date he has more than 160 appearances for the club, scoring eight tries overall.
Joe, from Eastbourne, was educated at Maynards Green Primary School and Heathfield Community College and began playing aged 11 for Eastbourne Sharks.
His stepping stones in the game not only include playing for Sussex Under 14-18 but also representing London & South East in 2006. Moving on, he played for England U18 in Argentina and in the IRB Junior World Championship in Japan.
He appeared in all ten competitive matches played by England U20 in 2010, scoring two tries in the 41-14 win over Wales at Kingsholm and one in the IRB Junior World Championship third-place play-off when England lost 27-22 to South Africa at Rosario that June.
Strong coaching influences on his game have included Will Stadler, his first mentor, followed by Tony Diprose and Ceri Jones, the former Harlequins loose-head prop.
Joe’s father Paul, who played for local club Hellingly, introduced him to rugby and to the front row where he has appeared throughout his career.
The former players that he especially respects are Nick Easter, Matt Ryan and Peter Bracken while his outside interests include cinema and golf.
His favourite ground is Roundstone Lane, Worthing and his best memory is a match for the Sussex club against Dings Crusaders.
