Sansone is a fast and agile forward with a slender physique and an eye for goal. He possesses good technique and dribbling skills, which enable him to take on opponents in one on one situations. He is capable of playing as a second striker, but his preferred position is as a left winger, a position which allows him to cut into the centre to strike on goal with his favoured right foot or make attacking runs into the area in order to create space for teammates.[21][22][23][24]
