Unai Emery praised Danny Welbeck for his versatility and said the forward has been training at left-back as Arsenal deal with an injury crisis.
Arsenal are likely to press in the early stages, if Emery's approach against Guardiola in the past is anything to go by.
Perhaps it was too much, too soon for a player who was an unused substitute in a Ligue 2 meeting between Lorient and Gazelec Ajaccio this time past year, but Lucas Torreira was not deemed fit enough to start and Emery is likely to be more concerned by the displays of some of Arsenal's senior players.
Arsenal still looked anxious and Cech nearly scored a freaky own goal when his miscued pass across the penalty area crept wide of his unguarded net.
"Our style with the ball is to be protagonists, to do things with combinations, to control the match with the positioning of the ball", Emery told Sky Sports.
When asked if City had fashioned a ideal performance, Guardiolan told the BBC's Match Of The Day: "Yes". Emery brought in goalkeeper Bernd Leno from Bayer Leverkusen this summer, as insurance in case Cech falters, so the current Gunners No. 1 knows he could lose his gig if he continues to struggle.
The anguish did not last long as Benjamin Mendy made his way to the byline and cut the ball back for Silva to emphatically find the top-left corner. The off-the-ball pressing became disjointed at times, but the intensity was there.
As for Arsenal, it is a fresh start for a squad that finished in sixth last season, its worst finish since the 1994-95 season, two years before Arsene Wenger took over as manager. It did however drag the mind round to Arsenal's real task: improving the quality of.
LONDON, ENGLAND - AUGUST 12: Petr Cech of Arsenal looks dejected after conceding Manchester City's first goal during the Premier League match between Arsenal FC and Manchester City at Emirates Stadium on August 12, 2018 in London, United Kingdom. Mesut Ozil enjoyed a largely uncharacteristic game in the final third while City's counterpressing did enough to stifle Arsenal and force them into quicker, unstable progressions.
Emery was not afraid to make bold changes during the game, either.
It seemed the goal might open the floodgates, but Cech was in solid form and kept the score down to just one. After years of Arsenal largely playing the same way regardless of the opposition, Emery's approach at the Emirates will be somewhat more reactive. "To help positions across the team with positive spirit".
