Arsenal coasted to victory at Bournemouth as captain Martin Odegaard's early brace took the visitors to the top of the Premier League.
The Gunners kept up their perfect start to the new campaign, their 3-0 win at the Vitality Stadium sealed with a fine William Saliba strike as the defender opened his account for the club.
Odegaard had put Arsenal clear inside the opening 11 minutes, the first time the Norway international has scored twice in a match since a double for Stromsgodset in October 2014.
At this stage of last season, Mikel Arteta was facing calls to be axed as Arsenal boss as they sat bottom without a point or a goal.
The summer signing of Gabriel Jesus has done much to herald such a stark turnaround in fortunes and, while he did not add to his goal tally on the south coast, the Brazil forward was again instrumental.
He plucked the ball out of the air with one touch, brushed off a challenge and fed Gabriel Martinelli, whose low shot was saved by Mark Travers.
However, Odegaard was on hand to turn home one of the easiest goals of his career to break the deadlock with less than five minutes on the clock.
Odegaard doubled the lead soon after, this time latching onto a loose touch by Jesus in the box and firing past Travers to set Arsenal on course for another three points.
Southampton came from behind to beat Leicester City 2-1 in their Premier League game at the King Power Stadium, as Che Adams scored twice after coming off the bench.
Following a goalless first half, Leicester took the lead in the 54th minute with a free-kick from James Maddison but super-sub Adams scored in the 68th and 84th minute to seal Southampton's first win of the season.
Adams scored nine minutes after coming off the bench, finding the target with a low strike following a long throw-in, while the hosts were left to rue their poor defending.
The Leicester-born Scotland forward then completed his double with an acrobatic effort as he volleyed home a cross from James Ward-Prowse, prompting boos around the King Power Stadium.
Adams almost bagged a hat-trick in stoppage time, but his shot rebounded off the post.
Earlier, Maddison had put Leicester ahead after he whipped the ball around the Southampton wall from a free-kick and found the bottom corner of the net, marking his second goal in three games.
Two goals from Wilfried Zaha and a late strike by Jean-Philippe Mateta helped Crystal Palace come from behind and defeat Aston Villa 3-1.
Mateta volleyed a fine cross from Tyrick Mitchell home from close range to wrap up the win in the 71st minute, with Palace having taken the lead when Zaha scored on the rebound after Emiliano Martinez saved his penalty.
Earlier, Ollie Watkins ran on to a pass by Leon Bailey and put Villa ahead in the fifth minute for his first goal of the campaign, but a vibrant Palace did not need long to respond.
Zaha found himself in space two minutes later and slotted the ball past Martinez to restore parity for Patrick Vieira's side, who could have gone in front had Jeffrey Schlupp's strike not been ruled out for offside.
Villa defender Lucas Digne handled the ball in the penalty area after the break and Zaha's initial shot from the spot was saved, but the Ivorian striker made no error on the rebound in the 58th minute.
Winger Demarai Gray fired a late equaliser to give Everton a 1-1 draw with Nottingham Forest at Goodison Park as they picked up their first point of the new Premier League season.
Forest gave a debut to club record signing Morgan Gibbs-White a day after he arrived from Wolverhampton Wanderers on a five-year deal and he led a lively raid down the left that almost resulted in a goal for Neco Williams.
Brennan Johnson gave Forest the lead in the 81st minute when he reacted quickest to steer home a rebound for his first goal of the season and looked all set to give his side their second victory in a row.
Gray had other ideas, however, latching on to a long ball from goalkeeper Jordan Pickford before confidently slotting the ball into the net to the delight of the home fans in the 88th minute to snatch a deserved draw for his side.
Aleksandar Mitrovic's last-minute powerhouse header snatched Fulham a 3-2 Premier League win over local rivals Brentford at a rocking Craven Cottage.
The Serbia striker converted Kevin Mbabu's teasing far-post cross at the last, just as Fulham were fearing to have squandered victory after surrendering the 2-0 lead they established inside the opening 20 minutes.
Marco Silva's men sealed their first win of the new Premier League campaign thanks to Mitrovic's second goal of the term.
