Cape Town - Four months after quitting Liverpool for Manchester City, Raheem Sterling will have the first opportunity to justify the move by getting one over his former employers when the teams meet at the Etihad Stadium on Saturday.
Sterling joined City in the close season in a deal worth up to £49m, but the circumstances surrounding the transfer left a bitter taste in the mouths of many Liverpool fans.
Sterling's relationship with Liverpool had soured in the lead up to the transfer after he gave an unauthorised interview to the BBC.
His agent Aidy Ward also angered the club by saying the England winger would not sign a new deal at Anfield.
Sterling has since said he has no regrets over quitting Liverpool and the Premier League table already offers some justification for the move.
