Arsenal took Daniel Farke's Leeds apart as they secured an emphatic 5-0 win that sent them to the top of the Premier League table but a double injury blow, that saw both Martin Odegaard and Bukayo Saka withdrawn, will be of significant concern ahead of the massive early-season clash with Liverpool.
After wasting a couple of early chances, with Viktor Gyokeres guilty of a particularly glaring miss, the Gunners were given a scare as Pascal Struijk saw a powerful header from a corner palmed over the bar by an alert David Raya.
With the hosts struggling to create many clearcut opportunities as Daniel Farke's side dug in and got numbers behind the ball, it was a trusty set-piece that finally served to break Leeds' resolve. Declan Rice launched in one of his trademark corners right into the danger zone, with Timber watching the ball onto his head and diverting a precise effort into the corner of the net.
And having broke the deadlock, Arsenal would be two up before the break. Saka, who was having an uncharacteristically quiet half, burst into the box in stoppage time after Rice had pressed high and won possession, smashing an effort past Lucas Perri, who hopeless flung up a right arm after the ball had already flew past him.
The Gunners' third goal brought a smile to Eberechi Eze's face, with the £60 million signing who was presented to the crowd before kick-off here gleefully applauding as Gyokeres got off the mark. The Swede, who was harshly criticised after an ineffective debut at Old Trafford, received a ball in the channel and cut inside before sliding past Perri and wheeling away to perform his trademark mask celebration.
The buzz created by the goal quickly turned to anxiety around the Emirates, however, as an apparent hamstring injury saw Saka leave the pitch after 53 minutes, with Odegaard having already gone off due to a shoulder issue. It's Liverpool up next for Mikel Arteta and his side who will be praying two of his big-game players make quick recoveries.
There would still be plenty of time to the dominant hosts to add to their goal tally, meanwhile, as Timber poked home a scrappy fourth as Leeds fell apart at a corner and then Max Dowman, making his Arsenal debut off the bench at just 15 years old, won a penalty that was smashed into the net by Gyokeres for his second of the night.
