The 22-year-old has been linked with Tottenham and Liverpool this summer.
“Micah is part of my plans,” Mancini told the Manchester Evening News. “He’s played here for four or five years, and I think that he must improve.
“He has everything to do his job, but sometimes his concentration lets him down. Sometimes, his body is on the pitch, but his head is not. But I think that if we work on him, he will improve.
“You have to remember that he is only young. It is better for him that we work to improve every day, because he has everything he needs to become a strong player.”
