It all started as a result of an incident during a Champions League match between City and Bayern Munich in Germany, when Tevez refused to come on as a second-half substitute.
Mancini was furious and Tevez was subsequently fined and suspended by the club. He responded by returning to Argentina and not playing again for six months.
He recalled to Fox Sports Argentina: “I regret the bad moment, but the truth is that I was right.
“The thing was like that, we are going to play Munich and Mancini put Kun Aguero as the only striker.
“At 10 minutes we are losing 2-0, and he turns to me and tells me to go warm up. I thought good; I'd get on in the first half, but no. I was running for 35 minutes.
“I thought I was going to come on in the second half because he told me to stay warm during half-time, but nothing…
“Fifteen minutes into the second half, I was warmed up, and I went to sit alone, I had been running for more than an hour.
“Then he turns around and tells me to warm up again, I said no, that it was crazy. After, in the conference, he said that I didn't want to play. He had everything already set up."
