De Jong was given a start against Arsenal on 12 September 2009. He was named Man of the Match by Sky Sports in a 2–1 win over Chelsea on 5 December 2009. By the end of the season he had become a firm fans' favourite as well as being one of new manager Roberto Mancini's first picks as defensive midfielder as the team narrowly missed out on a Champions League berth. De Jong scored his first goal for Manchester City in a 2–1 victory against West Ham United on 1 May 2011.
