Manchester City and Carlos Tevez have become embroiled in tit-for-tat threats to reveal who said what over the possibility of the South American extending his stay at Eastlands.
Amid the fall-out from revelations that Tevez had asked to leave City, it was claimed in a club statement that it is not their policy to conduct contract negotiations during the middle of a season.
However, as an increasingly bitter feud escalates, the Tevez camp have responded by claiming to have proof City were doing just that via an e-mail offer of a revised contract which was sent at the beginning of October.
City have said that talks had taken place, but over peripheral issues such as image rights, rather than a contract itself.
Blues officials are adamant Tevez's long-time advisor Kia Joorabchian is the major problem, given the downturn in his own relationship with the club.
They point to a succession of different reasons that have been put forward for Tevez's discontent as evidence of a shifting position from the South American.
Yet even they accept the bond between Joorabchian and Tevez is so strong it will not be broken, which makes their decision to single out the Iranian for personal criticism strange given it only increases the likelihood of them losing their skipper.
Tevez is due back to training on Tuesday after being given an extra day off by Mancini.
Given the deterioration in his relationship with the club, it was questioned whether the 26-year-old would actually turn up. However, it is understood he will be at Carrington as City begin preparations for Thursday's Europa League trip to Juventus.
Whether Tevez is on board the flight to Turin is another matter.
