Robinho joined City from Real Madrid for a British record £32.5million on transfer deadline day.
He said: “There’s a much better atmosphere in Manchester City’s dressing room than in Real Madrid’s.
“Every day I feel more united to the group.
“We want to do as well as possible this year and then play in the Champions League like I used to.
“I’m going to score as many goals as possible for Manchester City and look to show I’m worth the money they spent on me.
“The English fans will know who the real Robinho is within the next few weeks.”
