A Martin Odegaard brace within the opening 11 minutes set Arsenal on their way to the top of the fledgling Premier League table as Arsenal convincingly beat Bournemouth at the Vitality Stadium.
The Norwegian’s flying start put Arsenal in firm control of proceedings throughout, and Arsenal lead was trebled six minutes after the restart thanks to a fine William Saliba strike.
The result ensures Arsenal continue their 100% start with nine points out of nine, and leapfrog Manchester City at the division’s summit for the time being.
The opening goal came after five minutes, courtesy of a piece of Brazilian magic. Gabriel Jesus showed impeccable control and skill to take the ball high out of the south coast sky, beat two players and slip in Gabriel Martinelli, who saw his shot saved by Mark Travers but Odegaard was perfectly placed to tuck home the rebound.
And six minutes later, the dream start for Arsenal and their captain continued as he grabbed a second to put Arsenal in firm control. The overlapping Ben White just managed to beat the offside trap to fizz the ball low into the area for Jesus to again stop dead, and when it looked like he was about to pull the trigger, Odegaard whipped the ball off his toes and into the net.
The rest of the first half continued to be one-way traffic, with Aaron Ramsdale enjoying a quiet half on his return to his old stomping ground - indeed the Cherries failed to even have a touch inside Arsenal's box in the first half, let alone a shot at goal.
However, Arsenal struggled to carve out another clear chance, with Granit Xhaka having the best opportunity when he found himself in space following an Odegaard free–kick, but stumbled at the crucial moment.
Despite Arsenal's first-half dominance, the hosts knew that a goal for themselves would be a huge momentum shifter, and Jefferson Lerma rashly blazed over with their first attempt of the game not long after the restart, but he was quickly shown how it was done by Saliba.
On 51 minutes Arsenal won a free-kick on and Martinelli drove down the right before firing a cross over to Xhaka at the back post to lay the ball off to the Frenchman, who promptly curled it into the top corner to register his first goal in Arsenal's colours and clinch the win.
As it had been all evening, confidence was oozing through the team and Martinelli had a couple of chances to net his third of the season but screwed wide when being put through, before neatly juggling in the area and flashing a shot inches past Travers’ far post.
With 19 minutes to go, Jesus thought he’d got in on the act when he latched onto a delicious Odegaard pass and fired into the net, but after a VAR review he was deemed fractions offside, and Ramsdale was finally called into action to make a flying stop to deny a Kieffer Moore header spoiling his clear sheet.
Scott Parker’s team continued their late flurry and James Tavernier saw a low free-kick ripple the side-netting, but Bournemouth were indebted to Travers to keep it at 3-0 as he made good stops to deny Jesus and Eddie Nketiah late on.
However, the win had long-been secured, and with the clean sheet also in the bag, it meant Arsenal won their first two away league games without conceding a goal for the first time since 1993/94, and in the process moving Arsenal up to the Premier League summit.
