There appeared to have been a thawing of relations between club and player when it emerged Tevez was on his way back to City - having been holed up in Argentina since his controversial falling-out with officials last year.
However, on the eve of his return to England, Tevez gave an interview on Argentinian television where he claimed he had been "treated like a dog" by Mancini.
The City boss took issue at the comments and Tevez has been training alone upon his return to Carrington.
Mancini is preparing his side for a Europa League clash with Porto and he did not want to talk about Tevez.
"I am here to talk about Porto," he said when asked about Tevez's role.
And when asked if a meeting was planned with Tevez, Mancini said: "There is a meeting tomorrow, against Porto."
