Manchester City new-boy Carlos Tevez has had more to say about his former boss Sir Alex Ferguson.

According to the Sunday Mirror, the Argentine international has insisted that Ferguson was the reason he left Old Trafford and he admitted that he does not know whether he will shake his hand when he next sees him.

"There is no mystery why I left United and Alex gave me all the reasons to leave," said the striker. "I did not play an important role in any of the important games.

"In the Champions League I didn't play, I didn't play in the derby.

"I tried several times to speak to him, to express my feelings, but the only thing he'd say was 'don't worry, don't worry, this is going to change'.

"He never gave any justification or explanation - I don't know if I will shake his hand this season."

Tevez also went on to thank his Manchester United team-mates for all their efforts in attempting to make him stay.

"My team-mates tried several times to convince me to stay and that things would change," he revealed. "I'm always very thankful to them and we had a very good relationship, because we won a lot of things in two years."

Yet, despite his colleagues' protests, Tevez decided to swap the red half of Manchester for the blue and he believes that he can win trophies at City.

"If I didn't think that City would win titles, I could have stayed at home with my daughters," he added. "I want to give the best to help the team develop and win trophies."
