Champions Manchester City looked close to their sparkling best as they comfortably beat promoted Fulham 3-0 at the Etihad Stadium on Saturday to stay within two points of early leaders Liverpool and Chelsea.
Sane had been a surprise omission from Guardiola's regular starting line-up so far this season, having also missed out on Germany's World Cup squad.
The Englishman was crucial to City last season, scoring an impressive 18 goals in 33 appearances as the Citizens romped to the Premier League title with a record-breaking 100 points.
Despite going gown early, Fulham refuse to be intimidated by City's attacking threat and on the 20th minute, they nearly benefitted from Schurrle's run but after doing well to find Vietto, he took too long to makes a decision, allowing City defenders to fall back in shape.
Sterling broke from deep in his own half with a strong, skilful manoeuvre before David Silva's superb cross-field ball found Aguero on the right.
Manchester City has its full compliment of players aside from Kevin De Bruyne and Claudio Bravo who are out with long-term injuries. Saturday's meeting with City sees them match up against the side that sits second in the Premier League with 2,726 completed passes through four matches, 497 more than Fulham.
Fulham boss Slavisa Jokanovic said: "The result is completely fair".
The victory keeps defending champion City within two points of early leaders Liverpool and Chelsea, which both maintained flawless starts to the season.
He said: "It's well-known we're delighted with him and would like that to continue".
The hosts' best chance of a fourth goal came nine minutes from time when Jesus latched on to Kyle Walker's pass before teeing up Bernardo, who lacked composure despite being unmarked and blazed his effort well over when he should have done better.
"How we start the game, how we start the second half, it didn't make it easy for ourselves fighting for something positive".
But if you have a go like Fulham did yesterday, City will exploit the spaces and rip you apart. I understood when I watched them the reason why they are in the Premier League.
