"Mario has to stay calm because he has quality but still has lots of hard work to do," the Nerazzurri tactician insisted. "He can and should score more goals.
"He has to keep his feet on the ground. Today he scored two important goals, but he needs to carry on like this and always be looking to improve."
After his two-goal Coppa performance, Balotelli added: "I'm very happy and I want to thank Mancini for playing me from the start.
"I was very tired at the end.
"Maniche made a great pass for my first goal. I controlled it well, which was the most difficult thing, and I kept my cool.
"For my second, I trapped the ball and someone else was calling for it, but I decided to shoot and it went well."
