Gabriel Jesus is one of the top 10 most expensive teenagers in history following his £27m move to Man City.
The 19-year-old Brazilian is Pep Guardiola's latest recruit - but where does he rank among the other highly valued teens?
Here, we take a look at the 10 most expensive teenagers in history…
Anthony Martial (Monaco to Manchester United, £36m)
Anthony Martial became the most expensive teenager in history when, at the age of 19, he joined Manchester United for £36m in a shock deadline day move in summer 2015.
Luke Shaw (Southampton to Manchester United, £31m)
Shaw had been the most expensive teenager in history before Martial's arrival at Old Trafford. The former Southampton left-back joined United in the summer of 2014.
Lucas Moura (Sao Paulo to PSG, £28m)
The Brazilian forward has not exactly set the world alight since his big-money move to PSG. Now 23, he still struggles to hold down a regular starting spot for the French giants.
Renato Sanches (Benfica to Bayern Munich, initial fee of £27.5m)
One of the stars of Portugal's victorious Euro 2016 campaign, Sanches had been chased by a number of Europe's elite before Bayern won the race for his signature this summer.
Gabriel Jesus (Palmeiras to Man City, £27m)
Manchester City beat a number of top clubs to the signature of 19-year-old Brazilian forward Jesus. The teenager will represent Brazil at the Olympics in Rio then return to Sao Paulo-based Palmeiras for the rest of the year before linking up with Pep Guardiola's men.
Wayne Rooney (Everton to Manchester United, £26m)
The £30m spent on Rooney in 2004 remains one of United's wisest investments. United captain Rooney is closing in on Bobby Charlton's 249-goal club scoring record.
Javier Saviola (River Plate to Barcelona, £25m)
The Argentine striker arrived at Barcelona as one of the most exciting young talents in world football in 2001. He scored 60 goals in his first three seasons at the Nou Camp, but his career never quite hit the heights that had been expected.
Anderson (Porto to Manchester United, £22m)
It's fair to say Anderson was not exactly a storming success at Old Trafford. The Brazilian midfielder only made 10 appearances in his final two seasons at United and he now finds himself back in his homeland with Internacional.
Marquinhos (Roma to PSG, £22m)
Chelsea tried and failed to take Marquinhos to Stamford Bridge last summer. The Brazilian is rated as one of the best young centre-backs around, and PSG are unlikely to part with him any time soon.
Antonio Cassano (Bari to Roma, £20m)
Cassano was only 19 when Roma paid £24m to sign him from Bari in 2001. The Italian striker went on to have a colourful career, with spells at Real Madrid, AC Milan and Inter, among others.
