Manchester City stunned city rivals United with a 6-1 victory which takes them five points clear at the top of the Premier League.
Goals each side of half-time from Mario Balotelli gave City a 2-0 lead before last man Jonny Evans was sent-off for bringing down the Italian.
Sergio Aguero added a third, before Darren Fletcher struck a 20-year finish to show a more respectable scoreline for United fans.
However, it didn’t last long as Edin Dzeko scored twice and David Silva added his name to the scoresheet in injury time to secure a famous win for Roberto Mancini’s men.
