Pietro Pellegri's transfer from Genoa to Monaco is notable for many reasons, but mostly for his age and the size of the fee based on that.
Pellegri, 16, has made 10 first team appearances as scored three goals - including one to help spoil Francesco Totti's final Roma match - which was enough for the Ligue 1 champions to spend £18m to bring him to the Stade Louis II.
The price is a world record for a 16-year-old - and is the seventh record fee paid for a player based on age this season.
Examining the fees paid this season, new highs have been set for players aged 18, 20, 25, 26, 30 and 32 - and now, with Pellegri, 16.
