Arsenal, Chelsea, Liverpool and Real Madrid have young players hoping to make a major impact on the global stage at the 2014 FIFA World Cup.
Read the ten wonderkids we think will shine in Brazil here.
Thibaut Courtois (Chelsea)
Belgium
13 caps, 0 goals
Thibaut Courtois is just 21 years of age, but is already amongst the very best goalkeepers in world football.
Given the longevity of a career between the sticks compared to an outfield player, in theory Courtois could have fifteen years of football ahead of him for his country.
Courtois has made 41 appearances for Atletico Madrid this season, keeping 20 clean sheets.
His command of his area and lightning reflexes could be vital for Belgium this summer.
Serge Aurier (Toulouse)
Cote d'Ivoire
8 caps, 0 goals
Serge Aurier is a hugely promising young right back who has regularly been linked to Arsenal over the last year or so thanks to fine performances for Toulouse.
The 21 year-old has scored five goals and provided six assists in Ligue 1 this season, illustrating his enormous threat from the full back position.
The likes of Didier Drogba and Gervinho could thrive on Aurier's powerful forward runs and crossing.
Raphael Varane (Real Madrid)
France
5 caps, 0 goals
Raphael Varane is just 19 years of age, but only injury troubles have prevented him from adding to his five caps.
The imperious centre half has already made 60 appearances for Real Madrid, claiming La Liga title in 2011-12m and having helped his team win two and draw one of the last four El Clasico matches against FC Barcelona.
When fit, there is probably no better young defender in the game.
William Carvalho (Sporting Lisbon)
Portugal
2 caps, 0 goals
William Carvalho's stock has risen exponentially in the last few months, thanks to great spells for both Sporting Lisbon and Portugal.
While not blessed with explosive pace, Carvalho excels in his holding role thanks to positioning, great timing of tackles and both keeps possession and dictates play with his fine passing.
Paul Pogba (Juventus)
France
8 caps, 1 goal
Manchester United have needed to sign a dynamic central midfielder capable of playing between both penalty boxes, and while David Moyes presumably signed Marouane Fellaini to fill this role last summer, his predecessor Sir Alex Ferguson failed to see he already had a player capable of that role on his books in Paul Pogba.
The 6'1" midfielder left Old Trafford for Juventus in summer 2012, and immediately made an impact in the first team, earning his first Scudetto title after a fine debut season in Serie A.
In December 2013 Pogba won the Golden Boy award for the best young player in Europe, and he looks set for great success with both Juve and France in future.
Alex Oxlade-Chamberlain (Arsenal)
England
14 caps, 3 goals
Arsenal's Alex Oxlade-Chamberlain suffered a blow to his development when he lost five months of the season to a cruciate knee ligament injury.
The Gunners midfielder returned in January to brilliant effect though, and his three goals and five assists in 14 Arsenal matches this term are illustrative of his clear quality.
Against Bayern Munich in February, he put in a superb performance, dribbling past ten players - as much as the entire team of the Gunners' Bundesliga opposition - and he could prove a thrilling player for England in both central midfield and on the wing.
Mario Goetze (Bayern Munich)
Germany
27 caps, 7 goals
Mario Goetze seems to have been around forever, and at the age of 21 already has 27 caps and a €37 million transfer to Bayern Munich under his belt.
The diminutive playmaker is capable of playing both across the attacking midfield and even as a false nine, and is an increasing threat as a goalscorer.
With 10 strikes already in his 30 matches for the Bavarian giants, and having scored four times in his last seven international games for Germany, Goetze looks set to make a real impact on the summer's World Cup.
Raheem Sterling (Liverpool)
England
2 caps, 0 goals
Raheem Sterling has re-emerged in quite some fashion after being removed from the firing line by Liverpool boss Brendan Rodgers for much of a tricky 2013.
Upon receiving his first Premier League start of the season in December though, the 19 year-old Sterling has not looked back, and started England's last international fixture against Denmark.
With six goals and three assists already this season, Sterling has swiftly developed into one of the most exciting young players in the Premier League - and a man who could prove quite the wildcard for Roy Hodgson's England.
Joel Campbell (Arsenal - on loan at Olympiakos)
Costa Rica
31 caps, 9 goals
Joel Campbell signed for Arsenal in 2011, but after failing to win a UK work permit to play for the Gunners immediately, he went out on loan to FC Lorient in France, Spanish side Real Betis and finally to Olympiakos.
Campbell has scored 10 goals and provided 12 assists in his 36 matches for the Greek side this season, with his most famous strike coming against Manchester United in the last 16 of the UEFA Champions League.
The 21 year-old is now eligible to play for Arsenal, and his experience abroad and for his country at this summer's World Cup should serve him well.
Romelu Lukaku (Chelsea - on loan at Everton)
Belgium
27 caps, 5 goals
In the last two seasons, Romelu Lukaku has shown he will be a fine Premier League striker.
In spells on loan at West Bromwich Albion last season and Everton in the current campaign, Lukaku has scored 28 goals in his total 61 matches.
With just five goals for his country in 27 caps, Lukaku has taken time to adapt to the rigours of international football, but if he can step up in the World Cup, Belgium could be dark horses for the trophy.
