Football can be a daunting place for burgeoning professionals, especially when it comes to the highest level. The pressure, the media scrutiny and the sheer pace of the game have overwhelmed plenty of untested players over the years.
But fate is not always a cruel mistress to teenage hopefuls in top-flight football. Sometimes, whether by luck, skill or circumstance, there are those who have left their mark on a big match while not being legally able to celebrate it with a pint afterward.
Here are the five youngest scorers in Europe's top five leagues.
James Vaughan (Premier League)
With Everton cruising to a win against Crystal Palace at Goodison Park in April 2005, David Moyes decided to hand 16-year-old Vaughan his debut.
Defying expectations, the striker went on to prod home the fourth when he was just 16 years and 271 days old, breaking James Milner's record of the youngest-ever Premier League goalscorer in the process.
Although Vaughan's career hasn't quite gone on to dizzying heights, he is still playing for Sunderland in the Championship.
Fabrice Olinga (La Liga)
At a time when Málaga fans were reeling from the departures of Santi Cazorla and Ruud van Nistelrooy, Fabrice Olinga provided some much-needed excitement when he scored against Celta Vigo in August 2012.
Aged just 16 and 98 days, the Cameroon striker broke Iker Muniain's record when he got on the end of Diego Bounanotte's cross to score a dramatic late winner.
Nuri Şahin (Bundesliga)
Şahin became the youngest-ever Bundesliga player when he made his Borussia Dortmund at just 16 and 355 days in August 2005. Just three months later, he scored against Nuremberg to become the youngest-ever scorer.
Şahin's form saw him sign for Real Madrid, while he also had a loan spell at Liverpool before returning to Dortmund in 2012.
Amedeo Amadei (Serie A)
Although Genoa wonderkid Pietro Pellegri recently became the youngest player to score a brace in Serie A, it's Amadei who holds the overall record, having scored for Roma when he was just 15 and 287 days all the way back in 1937.
Amadei went on to score over 200 goals in his career and won the Scudetto in 1942, making 13 appearances for the Italian national side too.
Neal Maupay (Ligue 1)
Since the French league officially changed its name to Ligue 1 ahead of the 2002/03 season, Maupay has been the youngest-ever scorer.
It was an important goal, too, as he netted an injury-time winner for Nice against Evian as they recovered from two goals down to win 3-2.
Still only 21, Maupay signed for Brentford in the summer.
