A look back at the England squad that competed in the 2008 tournament shows that several of the backs division have gone on to become regulars at Guinness Premiership level but that it's proved tougher for the forwards to make the senior breakthrough.
2008 England U20 Forwards: Nathan Catt (Bath Rugby), Calum Clark (Leeds Carnegie), James Clark (London Irish), Alex Corbisiero (London Irish), Matthew Cox (Worcester Warriors), Hugo Ellis (London Wasps), Jon Fisher (London Irish), Scott Freer (Leeds Carnegie), Gregor Gillanders (Leicester Tigers), Joe Gray (Northampton Saints), Scott Hobson (Cornish Pirates), Courtney Lawes (Northampton Saints), Billy Moss (Bath Rugby), Ben Thomas (Saracens)
2008 England U20 Backs: Miles Benjamin (Worcester Warriors), Noah Cato (Saracens), Luke Eves (Bristol Rugby), Alex Goode (Saracens), Rob Miller (Newcastle Falcons), Mark Odejobi (London Wasps), Charlie Sharples (Gloucester Rugby), Joe Simpson (London Wasps), Seb Stegmann (Harlequins), Alex Tait (Newcastle Falcons), Jordan Turner-Hall (Harlequins), Ben Youngs (Leicester Tigers)
But as he embarks on his second World Cup with the England U20s, having been part of the 2009 squad who competed in Tokyo, the former Matson player is happy to wait his turn as his career develops.
"My aim is to establish myself as a regular first-team player," Knight said. "But as a tight-head prop I know time is on my side.
"I would rather it was sooner rather than later but I also know it doesn't work that way.
"Hopefully everyone else realises that too and doesn't expect me to burst through. I will give it everything."
After the World Cup in Argentina, Knight will travel to New Zealand to play for Manukau to gain some experience.
He is hoping the trip, as well as playing for his country, can continue his development as a promising member of the front row union.
"I'm going out to New Zealand after the World Cup to gain some experience out there then back in with Gloucester," he said. "I'll be out there for the start of the season on loan from Gloucester to Manukau.
"I'm happy to get the opportunity to do it, I can't wait for it. It will give me more game time, more experience and put me around different coaches and players.
"It can only help for learning new things and making me a better player."
Should Knight make it as a home-grown player into the Gloucester first team, he knows he would naturally have the support of the Kingsholm faithful.
That is if they can get any tickets ahead of the youngster's family.
"I was born and bred in Gloucester so all my family are from there," he said. "If I made the first team I would probably fill up near enough half the Shed with family.
"That's my goal, but I know it's a long way off."
