Neymar had only just turned professional in 2009 but his outstanding talent ensured he was expected to become a Brazil football legend. Watch Neymar at age 17.
We reported in June that Manchester City signed Barcelona midfielder Adria Bernabe and the player confirmed the move by changing his details on his Instagram account. The highly-rated playmaker initially joined the Catalans from Espanyol and was tipped for great things, but Bernabe should flourish under City manager Pep Guardiola and could surpass Phil Foden and Braham Diaz.
The 17-year-old has already slotted into the u18s and could get promoted to the reserve side if he develops quickly in his debut season with the Sky Blues.
