Bernardo Silva had just set up the opening goal for Manchester City with a sumptuous cross – a suggestion that last season's form might be starting to return.
But this was no time for the Portugal playmaker to rest on his laurels and he set about harassing Crystal Palace left-winger Jeffrey Schlupp, whose pass towards the danger zone where specialist centre-backs should reside was intercepted.
Rodri's outing in the heart of the City defence was unexpected and frequently uneasy during the early stages at Selhurst Park. A slip momentarily left Wilfried Zaha unattended before a rushed, hacked clearance went unpunished.
Pep Guardiola deployed his two defensive midfield commanders, Rodri and Fernandinho, in the back four due to Nicolas Otamendi joining Aymeric Laporte in the treatment room and John Stones not yet being match fit following an ailment of his own. City entered the field eight points behind Liverpool in the title race, with the decision not to replace Vincent Kompany starting to look season-defining.
But if being the last line of protection against attacks does not come naturally to Rodri, he specialises in starting them. His interception from Schlupp doubled as an expertly cushioned pass to David Silva and City were away.
Kompany's successor as club captain deposited the ball at Kevin De Bruyne's feet in unfussy, one-touch fashion. Where the 2-0 loss to Wolves played out under a fug of doubt and laboured decision making, the whirring cogs of Guardiola's machine were clicking into place.
De Bruyne promptly pushed down the accelerator, powering through midfield. The Belgium star, who did not start either of City's league defeats in the opening eight games, had already proved a menace to Palace. His twinkling triangle on the right flank alongside Bernardo Silva and Joao Cancelo provided a persistent first-half threat.
A great gift of De Bruyne's, a player on record as saying he prefers assists to goals, is he knows when to slip from leading man to supporting character. He found the opening goalscorer Gabriel Jesus.
The Brazil striker's scruffy diving header a little over a minute earlier was his fifth in as many starts for City this season. But the presence on the bench of club-record goalscorer Sergio Aguero – a man not so clinical behind the wheel on the road to training going off this week's evidence – means Jesus must always strive, always prove himself and always make the decision to please his manager.
A pass to the buccaneering Benjamin Mendy was just that. Fit again, for now, the left-back and his ravaged knees provide Guardiola with an extra dimension he will need if a third Premier League title in succession is to be achieved despite early arrears.
Mendy's touch was heavy but he was fortunate to see the ball fall to Raheem Sterling, Manchester City's sure thing.
Goals 12 and 13 of the season for club and country came as England routed Bulgaria in midweek, Sterling revelling in tormenting those who send vile abuse his way.
An inspirational figure with improvement still in him – as evidenced by a couple of second-half attempts against Palace – Sterling's chipped pass over the top of the home defence was a new string on his bow drawing the sweetest sound.
It was a pass worthy of David Silva, who on this occasion watched the whole move unfold and found himself on the end of it. For all their discomfort over the early weeks of this campaign, operating without their long-time creator and magician will really sting City this time next year.
His clinical over-the-shoulder volley through Wayne Hennessey's legs was equal to many of his finest moments over a wonderful decade in the Premier League and crowned a little masterpiece. 2-0 was enough for the three points.
Second-half wastefulness and Ederson's athletic stops from Christian Benteke and Wilfried Zaha showed City will have to be sharper in their next Premier League away game. That's at Anfield next month, but after talking about putting his players in the fridge over Christmas, Guardiola will have seen enough in a cool, calculated gem of a goal to suggest there is life in this title race.
