Wolverhampton Wanderers ran them close, but Manchester City started their Premier League campaign with a 3-1 win at Molineux on Monday night.
Pep Guardiola's side began their season a week later than most Premier League teams after their involvement in the Champions League in August.
Kevin De Bruyne won and converted a penalty to give them the lead in Wolverhampton before Phil Foden added a second goal before half time.
After City's first-half dominance, Wolves rallied after the break, creating a number of opportunities to get back into the game.
Raul Jimenez spurned an excellent chance from Adama Traore's low cross, but the Mexican striker made amends with a headed strike later in the half.
In the closing stages, Guardiola handed Ferran Torres a Premier League debut, sending the former Valencia forward on for Raheem Sterling.
Despite pressure from the hosts, City added a third goal in stoppage time through Gabriel Jesus to earn their first three points of the season.
