Arsenal v Leeds live: Saka off injured after Gyokeres goals and Dowman debut in Premier League thrashing

There were some worries for Arsenal as Bukayo Saka and Martin Odegaard both hobbled off injured.

Saka pulled up when running at full speed and went down appearing to hold his hamstring. The England international looked frustrated as he hit the deck and seemed to know that he had done some damage, as he was immediately replaced by Leandro Trossard.

Meanwhile, Odegaard went off with a shoulder injury in the first half. The Norwegian midfielder tried to initially play on but, with 38 minutes played, he was forced off – replaced by Ethan Nwaneri.

"Martin looks like a shoulder issue so we will have to scan tomorrow and understand how bad it is,” Arteta told Sky Sports. “And Bukayo had to come off after sprinting and when he was wrestling with the defender he felt something in his hamstring. It is the other side [to the previous injury] but it is still not good.

"I don't know [how long they will be out]. We already lost Kai [Havertz] which is a big player for us and now Bukayo and Martin. That is why the squad has to be well-equipped. It is going to be a long season and we are going to need a lot of players in order to achieve what we want."

Mikel Arteta was understandably pleased with Arsenal’s big win.

Speaking to Sky Sports, the Arsenal boss said: "A lot to be excited by. A really positive afternoon to start the season off at home, You could feel the energy immediately, that it had gone up a level and that is what we were looking for. The team played really well, really confident. The team created a lot and did not concede anything. Five goals and a clean sheet is a really good start.

"We have abilities to score in various ways. Very happy for Viktor [Gyokeres] scoring his first two goals and Jurrien [Timber] too for his two goals after such a long injury and hard work. Then the other debuts of Mosquera and Max at just 15 years old, that was special for sure."

On Dowman's debut: "We have to gather all the information. It's how he reacts and deals with the situation. What his teammates think about him, which is clear, because they kept on passing him the ball. It is great to be able to change the energy in the stadium by bringing him in and he had an impact. He won a penalty on his debut at the Emirates, that's incredible.

"It's credit first of all to his family, the way these kids have been raised and the environment created. They are not overwhelmed by the environment and context. And the work of the academy, for helping to raise these kids in that manner with the confidence and understanding of the game at just 15 years old."

Arsenal suffered a potentially huge blow as Bukayo Saka hobbled off injured during their dominant 5-0 Premier League win over Leeds United.

The Gunners brushed aside newly-promoted Leeds with two goals from Jurrien Timber, both from corners, a brace from big-name summer signing Viktor Gyokeres and a powerful finish from Saka himself just before half-time.

But the day turned sour when, early in the second half, Saka pulled up when running at full speed and went down appearing to hold his hamstring. The England international looked frustrated as he hit the deck and seemed to know that he had done some damage, as he was immediately replaced by Leandro Trossard.

The future looks bright for Arsenal. Hoping for it to be “fourth time’s a charm” in their pursuit of Premier League glory, a flawless start to the new season feels imperative. It meant a home victory over newly-promoted Leeds United, in itself, was not so much a headline as it was an expectation. Instead, the stories of the day centred around a select few individuals, those that spark visions of rediscovered success.

Arsenal fans begun the afternoon on tenterhooks, waiting for the imminent confirmation of new arrival Eberechi Eze from Crystal Palace. They wouldn’t have to wait long. The Gunners’ new No 10 was unveiled to the Emirates faithful prior to kick-off to raucous reaction, returning to club he grew up playing for and supporting.

To call this a homecoming, as was proclaimed over the PA, might be inaccurate - Eze was of course dumped by Arsenal as a teenager, something not fitting of a nurturing home. But as the 27-year-old calmly waved to his new fans, he let out a wry smile, almost as if to stick it to those who lost faith in his 13-year-old self all those years ago. That mistake has just cost Arsenal £60m.

Eze could well be the final piece to Mikel Arteta’s title-dreaming puzzle. He is exactly the player they need, a dribbler with creative spark who can break down the most stubborn defences. Yet his acquisition has already become something more of a necessity rather than a luxury.

Here’s how Jurrien Timber reacted to his two-goal day at the Emirates.

Speaking to Sky Sports, Timber said: "Special day! A nice first home game of the season. You felt the energy from the crowd. Clean sheet again is important."

On scoring two goals: "I don't think I have done that to be fair. God is good - all glory to him."

On Max Dowman: "I think everyone can see the potential he has. Playing today against grown men. He is a joy to watch, for the crowd too he is a joy to watch. Hopefully, he will have many amazing years here."

Here’s how Arsenal rounded things off, with a Viktor Gyokeres penalty

Dominance for Arsenal as they cruise to a 5-0 win. A busy, busy day as Viktor Gyokeres scored twice, as did Jurrien Timber, while Bukayo Saka also netted but hobbled off with a concerning injury and 15-year-old Max Dowman made his debut for the Gunners.

A poor, poor day at the office for Leeds though

Was there a temptation to give it to Dowman? Arsenal fans were chanting his name... It’s Viktor Gyokeres anyway.

He looks calm as he steps up and hammers it home! A perfect day for Arsenal.

And Arsenal have a penalty! Max Dowman jinks on the edge of the area, Stach pokes a leg in and there’s contact as the 15-year-old goes to the ground. Penalty says the referee!

Who will take it? Gyokeres or Rice the likely lads.

Into five minutes of added time now
