The former Juventus striker is now off the mark for his new club.
“He's a great player who scores 20-25 goals every season," Kessié told Sky Italia.
“That's what we need, he gives a lot to the team and it does so much knowing we can rely on giving him the ball. It's normal for a team like Milan to have that kind of striker.
“His mentality is to win every time, and he can help the squad in that way too. We must always go onto the pitch with that mentality, like him."
