City had taken the lead through Jolean Lescott's headed goal at the end of a first half that the Gunners had largely dominated.
Then, in a turn of events that mirrored the first half exactly, Arsenal played second fiddle to the champions and had to rely on their centre-half to score against the run of play to earn a deserved draw.
The result extends City's unbeaten run at the Etihad Stadium to 32 games, but it could have been so different had Arsenal taken advantage of their superior play during the first 45 minutes.
Once again, Santi Cazorla was Arsene Wenger's chief architect and put in an assured performance that will surely have caught the eye of Vicente del Bosque as he prepares to select his Spanish squad ahead of the World Cup qualifiers in October.
Roberto Mancini's team selection was full of surprises with Sergio Aguero returning to the fray much earlier than expected, while Carlos Tevez, City's best player this term, found himself dumped to the bench.
It would appear as if the Italian is struggling to deal with the pressure of expectation that comes with being champions. His strange selection against Arsenal makes this the third time he has made hugely significant changes to his starting XI in just seven games so far this season.
In the end, a draw was a fair result.
Arsenal were the better side in the first half and conceded against the run of play, while City were the better in the second half and also conceded against the run of play.
Here, we look at the player ratings for both teams in a game where that single point could yet prove crucial as far as the title is concerned.
