Carlos Tevez returns to England on Tuesday but has accused Manchester City manager Roberto Mancini of treating him "like a dog" in the incident which sparked the rift between club and player.
The striker claimed Mancini was in a foul mood and swore at him as he sat on the bench during the Champions League defeat at Bayern Munich at the end of September.
Talking about the circumstances surrounding his refusal to warm up on September 27, the Argentina international said in a Fox Sports interview broadcast in translation on Sky Sports News: "I was kind of in a bad mood and when he brings on (Nigel) de Jong and takes off (Edin) Dzeko and we're losing 2-0 I thought it was a defensive substitution so I decided to sit back on the bench."
He added: "I had already warmed up for 10 minutes and he has this attitude that he wants to lose 2-0 instead of 4-0.
"So I sat down and at the same time Dzeko comes off and is really angry and has a go at Mancini. He then sees the tunnel is closed so he has to sit down next to him and they start to have an argument.
"Dzeko was speaking Bosnian and Mancini would swear at him in Italian so it was a real mess.
"So I go and sit down and he doesn't see me because he's having this discussion. But then he turns around and sees me and you can imagine what happens.
"He's in the middle of an argument so then he tells me to keep on warming up and treats me like a dog.
"So when he spoke to me in that tone of voice, and I said 'No, I'm not going out'. So I was willing to play, but the coach was in such a foul mood because he had that argument with Dzeko.
"He started on me as well, started swearing at me, that was him, because I was very calm. I was just sitting on the bench and you can see from the footage that I was calm and just talking with (Pablo) Zabaleta. Mancini said some horrible things to me."
