The Argentina striker handed in a transfer request over the weekend, which was rejected by the Eastlands outfit, claiming his relationship with senior figures at the club had broken down. And Joorabchian, Tevez's advisor, is furious that the club have presented the forward's request as an effort to secure an improved contract.
Joorabchian told The Sun: "Garry Cook thinks he is bigger than Carlos Tevez. He is trying to make this an issue between him and me when it should be nothing of the sort. He might feel that he is a very important person but he isn't. Me and him aren't important enough. It's about Carlos and his relationship with the club."
Joorabchian also suggested that there are emails that prove City approached Tevez about a new deal, rather than the other way around.
"City say they have emails saying this is all about money," he said.
"They made Carlos a very generous offer which he rejected and there are many reasons for that. But I can tell you that there is no financial reasoning behind Carlos' decision.
"They can publish the emails if they want to but they have to do it in their correct chronological order and then everyone will see we have acted in a professional manner and have nothing to hide."
Joorabchian was also quick to reassure fans that Tevez will continue to give his all for Roberto Mancini's side while he remains with the club.
"He is a pro and will continue to play and give 100% as he has always done," added Joorabchian.
"It has been said City will sue for a breach of contract but on what grounds? All he's done is simply request a transfer."
