Aguero two goals on Sunday helped FA Community Shield defeated Chelsea to win their fifth FA Community Shield at the Wembley Stadium.
It was a good start for City and Aguero whose two goals ensured his 200th goal for the club.
The traditional curtain-raiser to the new English football season is game between title winners and Cup holders.
Pep Guardiola had said he was “starving” for more success and his team looked ravenous. Another trophy has come their way, albeit a fifth of importance that they will contest this campaign, but the resonance went far beyond.
Chelsea fell in spite of the arrival of Maurizio Sarri as Blues manager and new signing Jorginho.
Aguero struck his first on 13 minutes after Phil Foden, filling in admirably for Kevin De Bruyne, burst forward to find the Argentine.
He wrong-footed Antonio Rudiger with a low shot to become the first Manchester City player to reach a double century of goals, while John Stones continued his imperious form from the World Cup, just three weeks to the day after returning from Russia, and Bernardo Silva looked like a player trying to prove a point. The only disappointment was an indifferent performance from £60million signing Riyad Mahrez and the confirmation if any were needed, that goalkeeper Claudio Bravo is not going to be challenging Ederson for his place.
Chelsea, who were without Eden Hazard, took 25 minutes to even register a shot and rarely threatened.
