In July 19, 2009, at the age of 12, Baldivieso became the youngest player in professional football history when his father, Julio Baldivieso, who coached Club Aurora at the time, sent him on as a late substitution against La Paz. The match ended in a 1-1 draw.
Baldivieso's father, who was also his coach, decided to give him a start instead of one of his older brothers because he wanted to prove to the other parents that children could be allowed to play professional football if there were no injuries involved. Baldivieso came on as a substitute in the 79th minute and played for about 10 minutes before being replaced by his older brother Edgar.
Despite his young age, Baldivieso already has several years of experience playing football. His father took advantage of this by letting him play with older boys so that he would learn the game properly. He started out with Club Aurora, but after just one season he moved to Europe to continue his career with Belgian club Lierse S.K..
Baldivieso made his debut for Lierse in the UEFA Cup first qualifying round against Maltese club Hamrun Spartans. He came on as a substitute in the 73rd minute and helped his team win 2-0. This was followed up by another victory in the next round over Cypriot side Ayia Napa FC.
Brazil's Pele Pele against. The 17-year-old not only became the youngest player ever to participate in the World Cup finals, but he also became the youngest player ever to score a hat-trick in a World Cup match. The incredible triad occurred during Brazil's semi-final match against France, with Pele scoring his hat-trick in just 23 minutes.
The young striker Barthez had already scored twice when he was replaced by Zidane after 69 minutes of play. But what happened next was even more impressive than that first goal from Barthez! In the second half of the same game, Zidane returned to the field as a substitute and helped his team win 3-1. He made him only 16 years and 328 days old at the time.
It took until November 2, 1999 for someone else to repeat Pele's feat. Dutch teenager Marco van Basten scored a hat-trick for Italy in a 6-1 victory over South Korea at the 1999 FIFA World Cup. He was only 15 years and 311 days old at the time.
Since then, no one has been able to beat this record. However, there have been several players who have scored two goals in a single match while being a youth international, most recently Alex Morgan and Deulofeu.
When Jude Bellingham came on for England on Sunday, he became the youngest player ever to compete in a European Championship. In his team's opening game of the tournament, against Croatia, the 17-year-old came off the bench to replace Harry Kane. England lost that match 2-1 but went on to reach the quarter-finals.
Bellingham becomes only the second teenager to appear for England after Scott Parker, who also did so in a European Championship match. The England squad features eight teenagers including seven players under 21. Three of them - Kyle Walker, Eric Dier and Jordan Henderson - have been included in Gareth Southgate's side for this summer's World Cup in Russia.
England face Germany on Saturday with Southgate hoping his young stars can help him win his first international tournament. "We've got some very talented youngsters in the group," said Southgate. "They're ambitious to do well and I'm excited by their attitude."
Bellingham made his international debut as a 71st-minute substitute in Croatia where he showed great composure by scoring England's first goal of the tournament after just three minutes in the spotlight.
He became the third son of former England captain John Bellingham to represent his country after Jamie and Jordan are also members of the squad. The youngster has been given the number 10 shirt for the tournament.
Other players acknowledged today who debuted early were Welshman Gareth Bale, who debuted on October 7th, 2010 at the age of 17 years and 83 days, and Belgian Romelu Lukaku, who debuted at the age of 17 years and 113 days. Angel Zubieta, who was 17 years and 9 months old in 1935, was the youngest Spaniard to accomplish so.
Zubieta had a successful career with Sevilla and Barcelona and played in one World Cup, which was Spain's first trip to the tournament in 1950. He died at the age of 36 after suffering from tuberculosis.
Bale has been called many things since debuting for his country: the new Pele, the new Maradona, even the new Ronaldo. But perhaps what's most important to note about him is that he's still only 23 years old. He made his international debut at the age of 17 years and 83 days and has gone on to become one of the best players in the world. His goal tally stands at 26 goals in 77 appearances for Spain.
Lukaku made his international debut at the age of 17 years and 113 days and has gone on to score 31 goals in 87 appearances for Spain. He's the second-youngest player behind Bale to have scored in each of Europe's top five leagues (behind only Cristiano Ronaldo).
In addition to playing for Spain, Lukaku also featured for Everton during his time there.
