Kean spoke to the New York Times about his impressive form this season.
Asked if he believes he can be the top scorer in Serie A this term: "Why not? It's something that motivates me, it's one of my goals. I like challenges and the one between me and (Mateo) Retegui (top of the table with 11 goals) is great because it's nice to have a bit of a challenge.
"If you don't have anyone pushing you, it's not as motivating."
Kean also said, "So many things have changed since I arrived here, like the prospects I have. Florence, as a city, believes in me and this has given me that extra boost to improve and do well. I watched some videos of (Gabriel) Batistuta and (Luca) Toni when I arrived.
"Florence has always been a great football city and this means a lot to me. The fans really take you into their hearts. They care about the shirt. They give you absolute warmth.
