The Nigeria international moved to Torino on a season-long loan last summer in search of regular first-team football.
Aina’s versatility means he has featured predominantly as a wing-back in Mazzarri’s 3-5-2 formation this season with 27 Serie A games to his belt, including 20 starts.
“The football is very tactical. Everyone seems to think Italian football is slow and boring, just passing. But it’s not like that at all. There's so much that I didn't expect, and the football is really good.”
Aina has been at Chelsea since his teenage years and currently has two years left on his contract with Blues.
When quizzed whether he would consider the option to remain with Torino, he said; “Why not?
“It’s a good fanbase. It’s a very cultured club. You can tell by the fans and how everything is run here. It’s a nice place to be and I am very happy right now.”
On Sunday, the 22-year-old was introduced as an 87th-minute substitute for Tomas Rincon as the Bulls defeated AC Milan 2-0 in a Serie A fixture.
