Victor Osimhen has become the highest goal scorer in Serie A, making him the first African to do so.
He is also the first player since 2009 to combine that with the Scudetto.
Martinez has 21 goals and cannot go any higher, while Osimhen has 25 goals and cannot be caught.
Osimhen is the fourth Napoli player to win the award, following in the footsteps of Diego Maradona, Edison Cavani, and Gonzalo Higuain.
Napoli won the Scudetto for the first time in 33 years.
