Manchester City made their points on and off the pitch as they turned up the title heat on Arsenal.
The reigning champions, in their first game since being hit with over 100 financial charges by the Premier League, are now just three points behind current leaders Arsenal ahead of their trip to the Emirates Stadium on Wednesday.
After fans booed the Premier League anthem, cheered manager Pep Guardiola and held banners hitting out at the investigation, City raced into a three-goal lead by half-time thanks to a Rodri header, Ilkay Gundogan's close-range finish and Riyad Mahrez's penalty.
