France-born Bennacer joined Milan from Empoli in 2019 and has, over the past two seasons, become one of the key members of the team who are currently leading Serie A.
"Even if sometimes we see that he's screaming on the pitch, it's better than if he didn't say anything, otherwise it would mean that he doesn't care," the 23-year-old told AFP.
"He brings us a lot. With all the experience he has acquired, he tries to take us to the highest level with him, he always seeks perfection. He gives us a lot of advice."
The 39-year-old Swedish star has been a talismanic figure since returning to Milan in January 2020, reviving the fallen European giants.
