Manchester City’s title hopes suffered a setback as they drew at struggling Norwich to move nine points behind leaders Leicester with nine games left.
Canaries keeper John Ruddy kept out two Sergio Aguero efforts as the home side resolutely kept the visitors at bay.
However, it was Norwich who came closest to a goal when a 25-yard Patrick Bamford shot hit the crossbar.
The home side might even have snatched a late winner but Graham Dorrans put a shot wide when well placed.
Manchester City have now won only two of their past 11 away games in the league, and Manuel Pellegrini’s side failed to respond to his warning they had no “margin for error” in the title race.
