Ranking the 5 greatest Golden Boy award winners 

#3 Sergio Aguero (2007, Atletico Madrid)

Sergio Aguero was the Golden Boy winner in his first season with Atletico Madrid.

Sergio Aguero won the 2007 Golden Boy award as a 19-year-old in his first season at Atletico Madrid. However, his remarkable performances for Independiente in Argentina the previous season played a key role in Aguero winning the trophy. The striker scored 18 goals for the club in 36 league games before joining Atletico Madrid in 2006.

More than a decade later, the 2007 Golden Boy winner is regarded as one of the greatest strikers in the game's history. After netting 100 goals for Atletico Madrid, Aguero went on to become the all-time top scorer for Manchester City, netting 260 strikes. He is also the fourth-most Premier League goalscorer, with 184 goals, all for City.

Unfortunately, it seems, Aguero's career may be coming to a premature end, as he was recently diagnosed with a heart condition. Unconfirmed reports suggest the 33-year-old's retirement is imminent.

#2 Wayne Rooney (2004, Everton/Manchester United)

Wayne Rooney (#8) was the second player to win the Golden Boy award.

England and Manchester United legend Wayne Rooney was the second Golden Boy winner after the award was introduced in 2003. After making his Everton debut in 2002 as a 16-year-old, Rooney made 40 appearances across competitions for The Toffees in 2003-04. He scored nine goals and provided a solitary assist.

A blockbuster transfer to Manchester United followed, and Rooney enjoyed a dazzling start to his Red Devils career. He scored a hat-trick on his Champions League debut. Rooney ended the 2004-05 campaign with 17 goals in 43 games across competitions, and was named the Golden Boy award winner.

The rest is history. By the end of his decorated career, Wayne Rooney had scored 250 goals for United to become the club's all-time top-scorer. He is also second on the all-time Premier League scoring list with 208 strikes. While Harry Kane is breathing down his neck, Rooney is still England's top scorer with 53 goals.

#1 Lionel Messi (2005, Barcelona)

Lionel Messi became the third-ever Golden Boy winner in 2005.

One of the earliest accolades of Lionel Messi's glittering career was the 2005 Golden Boy award. It was also one of the first battles of what would become football's greatest rivalry. The Barcelona man was named winner of the Golden Boy title over Manchester United's Cristiano Ronaldo.

Messi's stats in 2004-05 weren't particularly impressive, as he made nine appearances for Barcelona as a 17-year-old, scoring once. However, he burst onto the scene the next season, making 25 appearances while registering eight goals and five assists.

A decade and a half later, Lionel Messi has won six Ballon d'Or awards and 35 trophies with Barcelona, scoring over 750 goals for club and country. The little magician is undoubtedly one of the greatest players to have graced the game.
