Former Crystal Palace manager Alan Pardew branded David Silva's opening goal against Leicester an 'injustice' after Raheem Sterling took up an offside position.
Leroy Sane's low cross found Silva who fired past Leicester keeper Kasper Schmeichel to open the scoring in the 28th minute at the Etihad.
Sterling veered into an offside position as Silva struck for goal with several Leicester players appealing to referee Robert Madley that the City forward got a touch.
The good stood, however, provoking a furious response from the visitors.
