Mancini has confirmed that he expects the Argentina international to return to the club on Thursday or Friday.
Tevez has been been in Argentina after being given a compassionate leave as his partner gave birth prematurely to their daughter.
“I spoke with him yesterday and I think that he will come back on Thursday or Friday morning,” Mancini said on Tuesday.
Mancini continued: “It is important Carlos comes back Thursday or Friday so he can play against Chelsea. He said to me that every day he has been training in Argentina, every morning.
“He had a serious problem but now I think he resolved his problem.”
