Unai Emery suffered defeat on his Arsenal debut as Manchester City kicked off their title defence with a 2-0 victory at the Emirates Stadium.
Raheem Sterling capped a relentless start from the reigning champions with his 50th Premier League goal inside the quarter-hour mark before Bernardo Silva secured the win with an exquisite second on 64 minutes.
Emery has been tasked with taking Arsenal to the next level after Arsene Wenger’s departure at the end of last season – but it was a familiar, disjointed performance from the Gunners, who visibly need time to adapt to their new manager’s philosophy.
For Pep Guardiola and City, it was business as usual as they took their place among the Premier League’s early pacesetters having started the defence of their crown with an eighth consecutive opening-day triumph.
