Liverpool have signed 16-year-old midfielder Harvey Elliott from Fulham.
Harvey Elliot made history when he became the youngest ever Premier League player at 16 years and 30 days old.
The England under-17 midfielder made his first appearance in the 88th minute of a game between Fulham and Wolves in May 2019.
Elliott became Fulham's youngest player in September 2018 in the Carabao Cup at just 15. He had broken the previous record by 38 days.
The England youth international cannot turn professional until his 17th birthday next April.
But he's not the first young sporting superstar to make a name for themselves from an early age.
Sixteen-year-old Celtic player Karamoko Dembele made his debut in the Scottish Premiership in May 2019 with a 2-1 win over Hearts.
Dembele came on as a half-time substitute and helped his team win the Scottish Premiership trophy.
Manager Neil Lennon said at the time: "The kid is 16 and we just want to develop him in the right way. He has been training with the first team and I had no hesitation giving him 45 minutes."
Before Harvey Elliot, Matthew Briggs held the record of youngest person ever to play in the Premier League.
He made his Fulham debut aged just 16 years and 65 days back in 2007, coming on as a substitute in their match against Middlesbrough.
He went on to play for Millwall and Colchester and in March 2018, it was announced that Barnet signed the defender on a non-contract basis.

"I didn't really know how to tell my schoolmates," she told BBC Breakfast. "But they know now and I've had lots of messages.
"It was just amazing walking out to a home crowd. It was really loud! I knew there was a chance of a medal so I just kind of went for it."
Everton player Theo Walcott became the youngest footballer ever to play for England when he played against Hungary in May 2006.

He went on to play for Arsenal for 12 years, where he scored 108 goals in 397 appearances, before moving on to Everton.

In February 2017, Leicester resigned the England fly-half paying a record fee between two English clubs to buy him out of his deal with Bath.
