With Tevez now looking increasingly likely to remain at City after Tuesday's transfer window has closed, Mancini felt the need to address comments made by the player's advisor Kia Joorabchian on Friday. Joorabchian claimed Tevez's relationship with his manager had never been good and there had been "feuds" with Mancini throughout their time together.
This has come as a surprise to Mancini, who has always got the impression he had a good working relationship with a player he made his skipper at the start of last season. "Carlos doesn't have any problem with me," said the City boss.
It has been claimed Tevez wants to join AC Milan, which is the reason why approaches from Inter Milan and Paris St Germain were unsuccessful.
All three clubs have now said they are out of the running during this transfer window, although it would not entirely be a surprise if there was a last-ditch attempt to sign Tevez from someone.
Presently though, the 27-year-old remains in Argentina, as he has been for over two months.
There have been suggestions he will return if his future is not sorted this week, leaving Mancini with a tricky problem trying to reintegrate a player in his squad who has taken such an extreme stance.
"Everyone should always answer for his behaviour," Mancini added.
"If a player is at one club and wants to go to another, it is an option for the player. Maybe for the club it is a big problem."
