One of the quartet will take the armband in Sunday's Premier League opener against Manchester City, given Koscielny remains sidelined with the ankle injury that ruled him out of France's triumphant World Cup campaign.
It's this weekend's biggest game - Unai Emery makes his League debut on the Arsenal bench.
Guardiola's side might become more technical at the back this season, with Aymeric Laporte and John Stones seemingly his first-choice combination, with the more rugged Vincent Kompany and Nicolas Otamendi back-ups. "We defended very well and were a very compact team".
But on the evidence of this composed display, City have every chance of emulating their rivals' achievement.
City's excellence underlined the size of the task facing new Arsenal boss Emery as the Gunners begin life without Arsene Wenger.
Cech made several saves to keep Arsenal in the game but also seemed to struggle a bit when playing with his feet, almost scoring an own goal in the first half when he mishit a back pass from Guendouzi.
Errors crept into City's play and Arsenal asked questions of their opponents before Bernardo Silva emphatically smashed into the top-left corner to make the points safe after the hour.
Guardiola insists his players are still "starving" for success and there is little doubt City's hunger for silverware remains strong.
Sterling bagged his 50th Premier League goal on Sunday (Aug 12) with a cool first half strike as the champions marked the start of the Premier League season with a 2-0 win at Arsenal. One crunching challenge on Arsenal new boy Matteo Guendouzi resulted in a booking, but the tackle was more enthusiastic than malicious.
However, Unai Emery has confirmed Mohamed Elneny is staying at Arsenal, and that only Carl Jenkinson, David Ospina and Joel Campbell are the ones close to departing the club this summer.
But that noisy optimism was punctured in ruthless style by Sterling in the 14th minute. Emery tends to shift between 4-3-3 and 4-2-3-1, but probably needs three solid midfielders against this City side.
The 27-year-old has struggled for regular football in recent times, either because of injury or the form of other players - with the likes of Pierre-Emerick Aubameyang, Alexandre Lacazette and Henrikh Mkhitaryan passing him in the pecking order.
Sterling and Mendy outnumbered Bellerin on the right, with the French defender's cross picking out Silva, who cleverly peeled away from his marker Stephan Lichtsteiner to fire past the exposed Cech.
The Democrat mayor of Los Angeles is surprisingly against the decision to remove President Trump's star from Hollywood Boulevard. The tweet was accompanied by a video , which showed "Faction" members installing the stars.
Arsenal are likely to press in the early stages, if Emery's approach against Guardiola in the past is anything to go by. We trained just one week. "He made some very good things in the World Cup, how he moved and created space for others".
Those birdies after his big blunder stood out to Finau, one of only 11 players to make the cut in all four majors this year. Eldrick Woods wasn't the only "Tiger" turning heads Saturday during the third round of the PGA Championship at Bellerive.
Teoscar Hernandez hit a two-run home run for the Blue Jays , his 17th, and Randal Grichuk added a three-run blast, his 15th. But Toronto evened the game at 2-2 in the home half of the first on a Justin Smoak single and a RBI groundout from Grichuk.

Tiger wakes up the echoes with best major final round
Brooks Koepka has a two-shot lead at the PGA Championship as he tries to become only the fifth player in history to win the U.S. Koepka wasn't fazed, just like he wasn't fazed by the firm and windy conditions that annoyed so many in the field at the U.S.
