City are on 53 points, seven clear of second-placed Leicester City, and with a game in hand.
And while there are 15 matches still remaining, it will take a major slump in form to stop City from claiming their third title in four years.
"It is a big step for us but of course it is not over," said Spanish midfielder Rodri.
Pep Guardiola's side are, however, playing with a swagger having now won 16 straight matches in all competitions and German Gundogan has been central to that record-breaking run of form with 11 goals in his last 12 Premier League outings.
