"Sergio is a special guy", said the Manchester City boss.
Chelsea are in the Community Shield after beating Manchester United for the FA Cup title.
It's not going to be an easy start to Sarri's reign, with doubts surrounding the future of star players Thibaut Courtois, Eden Hazard and Willian and with World Cup victor, Olivier Giroud, also rumoured to be on his way out, but Chelsea fans could be in for a treat this season.
From Pep Guardiola's passionate celebration of Aguero's opener, to his exasperation at Ilkay Gundogan missing the chance to make it 3-0 deep into injury-time, this was not just some pre-season warm-up for the City manager. Ahead of their latest meeting on Sunday, The Hard Tackle takes a closer look at the encounter.
Argentina worldwide Aguero had been stuck on 199 since he notched in the EFL Cup final victory over Arsenal on February 25, but he finally added to his tally in the first half to put Chelsea on the path to defeat in their first competitive match under Maurizio Sarri.
He will now compete with the likes of Jorginho, Fabregas and N'Golo Kante for a place in Sarri's usual 4-3-3 system. Sarri has completed two signings so far, with Jorginho and Rob Green joining the team. It may be early days but the ramifications of holding onto Antonio Conte while negotiations with Napoli over Maurizio Sarri rumbled on were there to see on the Wembley pitch yesterday. But, the Englishman is likely to start on the bench against Manchester City. But he did not specify who that player would be.
The positive note is that he can find the net when not at his best. Hailing Chelsea's summer business Morata said the Italian midfielder could become a key player this season.
This was not a City team firing on all cylinders - David Silva is not yet match fit after his exertions at the World Cup and Kevin De Bruyne and Raheem Sterling will not return to pre-season training until today - but that, if anything, is even more unnerving for their rivals. "That's why it's so good to have another player with his talent and he's a Manchester City fan, he's Mancunian, so that's why, for us, he's so good". "The schedule and results will show you who you are".
These will include Eric Garcia, Cameron Humphreys, Douglas Luiz and Lukas Nmecha.
Alvaro Morata, Cesc Fabregas and Pedro flatted to deceive against Man City and supporters just don't think they are good enough. The Blues have failed to win any of their last four appearances in the tie.
The annual curtain raiser to the start of yet another English top flight campaign sees the FA Cup holders Chelsea go head to head with Manchester City, the reigning Premier League champions.
That desire was matched by his team, who looked sharp, dominant and eager to assert themselves once again on English football as they rained 18 shots at the Chelsea goal.
