Arsenal moved back to the top of the Premier League as goals from William Saliba, Gabriel Jesus and Fabio Vieira put the gloss on a dominant performance as they beat Brentford 3-0.

Injuries to captain Martin Odegaard and Oleksandr Zinchenko had stretched Mikel Arteta's squad to the extent that 15-year-old Ethan Nwaneri came off the bench late to become the youngest player in Premier League history.

However, the Gunners showed no sign of weakness at a ground where they were beaten 2-0 last season to move back one point above Manchester City and Tottenham at the top of the table.

The match had been moved forward two hours to help ease police pressures around Queen Elizabeth's funeral and Britain's longest serving monarch was remembered in a minute's silence before kick-off.

Once the action did get underway, it was one way traffic for 45 minutes as Arsenal bounced back in style from their sole defeat of the season away to Manchester United two weeks ago.

Gabriel Martinelli should have opened the scoring within two minutes as he fluffed his shot from Granit Xhaka's cut-back.

It took just 15 minutes more for Arsenal to make the breakthrough when Saliba flicked Bukayo Saka's corner in off the far post.

Jesus also used his head to score his fourth goal in seven Premier League games since joining from Manchester City as he powered home another enticing delivery from Xhaka.

Saka was then wasteful with a glorious chance from Fabio Vieira's through ball.

The absence of Odegaard also handed Vieira his first Premier League start and the Portuguese midfielder made his mark with a sumptuous strike from outside the box to kill off any doubt over the outcome four minutes into the second half.

Brentford striker Ivan Toney had been handed his first England call-up in midweek but was kept well in check by the towering presence of Saliba.

The Bees will be hoping this was just an off day after an impressive start to the season and that Thomas Frank will still be in charge after the international break with the Dane linked as a potential successor to Brendan Rodgers at Leicester.

But an easy day for Arsenal was rounded off a minute from time when Arteta was able to hand Nwaneri his debut as just 15 years and 181 days, breaking Harvey Elliott's record as the youngest player in Premier League history when he appeared for Fulham as a 16-year-old.

At the other end of the table, West Ham will spend the upcoming international break in the bottom three after Neal Maupay's first Everton goal gave the Toffees a much-needed win.

Frank Lampard's men are now unbeaten in five league games but had just four points on the board before kick-off from four consecutive draws.

An injury to Dominic Calvert-Lewin forced Everton to seek more firepower in the final weeks of the transfer window and Maupay delivered on just his second appearance since a move from Brighton.

The Frenchman spun onto Alex Iwobi's pass and fired in from the edge of the area to lift Everton up to 13th in the table.
