The first fixture between Manchester United and Manchester City in the 2009–10 Premier League season was played on 20 September 2009 at Old Trafford.
It was the 153rd Manchester derby between the two clubs. Manchester United won the game 4–3 courtesy of a late winner from Michael Owen deep into second-half injury time.
Wayne Rooney opened the scoring early on, but a mistake from Ben Foster in the United goal allowed Gareth Barry to equalise for City.
Two goals each from Darren Fletcher and Craig Bellamy meant that the score was 3–3 going into four minutes of injury time, before Owen secured the win for the home side in the 96th minute.
The match saw the return of striker Carlos Tevez to Old Trafford after leaving United that summer.
After the game, United manager Sir Alex Ferguson described it as “probably the best derby of all time”.
In May 2012, the match was voted as the best of the first two decades of the Premier League in the Premier League 20 Seasons Awards.
