Scamacca is a tall, right-footed centre-forward, with an eye for goal, who is known for his explosive physical strength, and powerful shot, which allows him to score goals from both inside and outside the penalty area, even from acrobatic first–time shots. Despite his size, he is a technical player, who possesses flair and a good first touch, and is known for his tendency to drop deep, move freely about the attacking third, and link-up with his teammates, which sees him operate almost as a second striker at times, rather than as a traditional striker who mainly operates inside the box.[41][42][43][44] As such, he has occasionally been used in a role which is known as the centravanti di manovra in Italian football jargon, which is comparable to the modern false nine role, with Scamacca seemingly playing as a lone striker, but often dropping deep to participate in the build-up of attacking plays.[45] While effective in the air and at holding up the ball, due to his height and powerful physique, his aerial game has been cited as being in need of improvement by pundits, something which Scamacca himself has admitted, as he prefers to play the ball on the ground;[43][42][46][47] he was able to improve his aerial game during his time at Atalanta under manager Gian Piero Gasperini.[48][49] Although he is not gifted with significant pace, he is mobile for a player of his size.[50] Scamacca has cited former strikers Zlatan Ibrahimović and Gabriel Batistuta as some of his inspirations, and has even been compared to the former player by pundits due to his physique and playing style.[43][41][51] Once considered to be a promising player in the media, in 2016, he was named one of the "60 of the best young talents in world football" by The Guardian in 2016.[41]
