Arsenal vs Chelsea LIVE: Premier League score and goal updates as Leandro Trossard fires in opener

42 mins: Chance! Conor Gallagher gets into space on the right wing and swings in a cross. Nicolas Jackson comes bombing into the area and leaps towards the ball.

He takes his eyes off the ball which hits his arm and bobbles towards the near post. David Raya jumps across to push the ball away just as the whistle goes for handball.

39 mins: Enzo Fernandez lifts a cheeky cross into the penalty area from the inside right. Conor Gallagher sneaks in behind the defenders and almost has a tap in.

David Raya comes off his line quickly and scoops up the ball before Gallagher can reach it.

36 mins: From a short corner, Martin Odegaard tees up Bukayo Saka. He taps the ball forward then laces a shot over the crossbar.

33 mins: Kai Havertz lifts a cross in from the left wing and almost picks out Bukayo Saka. Marc Cucurella beats the Arsenal forward in the air and wins a free kick for Chelsea.

30 mins: Half an hour gone at the Emirates. Arsenal have been the more aggressive side but Chelsea have shown a bit of resistance in the last few minutes.

Should they score this one will only get more lively.

27 mins: Save! Petrovic makes up for his lacklustre attempt to keep out Trossard’s goal by denying Arsenal a second.

The keeper pulls off a sensational stop to keep out a Havertz cross that deflects off a defender at the last moment. It looks certain to drop into the corner but Petrovic gets across and keeps it out.

25 mins: Oh my! That’s wonderful from Martin Odegaard who tricks three defenders with his fancy footwork before slotting a teasing pass into the six yard box. Bukayo Saka misses the ball but it comes through to Ben White.

He rolls it off to Thomas Partey whose first time shot gets blocked and cleared.

Woodwork! Nicolas Jackson brings the ball under control and takes on William Saliba. He flies into the box and has a go, rattling the near post with his effort.

22 mins: Close! Arsenal are a different class. Declan Rice nicks the ball off Enzo Fernandez deep in Chelsea’s half. He checks to the right and smokes one at goal.

The effort is a good one but the ball continues to rise and flies over the top.

19 mins: A miscued pass back to David Raya from Bukayo Saka sends the ball out for a corner. Mykhailo Mudryk is the man tasked with sending it into the penalty area.

His cross gets flicked on and Axel Disasi just misses the ball for a tap in at the far post! That was a close one.

16 mins: Ben White wins a corner off Marc Cucurella. It’s the first one of the game and Bukayo Saka swings the ball into the penalty area.

Saka’s delivery is nodded away by Benoit Badishile but the ball is turned behind for another set piece.

This is is passed short before coming to Martin Odegaard who whips in a cross to the far post. Takehiro Tomiyasu arrives from deep and nods an effort high and wide.
