David Luiz goes for a David Luiz-esque effort, but his spectacular bicycle kick flies spectacularly wide of the intended target.

However, the Guynners then break with pace again through Reiss Nelson, who wins a corner.

Danger cleared by the Blues defence.

Arsenal regain possession - they seem happy to knock it about.

Qaaltagh: Both line ups and implied formations look atrocious. On paper, Wolves and Sheffield United look stronger than both of these teams. Top four places haven't been decided yet, far from it. But that's where Arsenal will end up - far from them, that's for sure.

Danger!

One thing I've spotted immediately is the high-pressing from Arsenal.

Mikel Arteta takes the applause of Arsenal fans as he walks to his seat in the technical area but no huge fanfare. Businesslike.

We are under way at a bright and sunny Emirates.

This is Mikel Arteta's first home game as Arsenal boss, and I am sure that will give everyone a bit of a lift.

But I just don't trust the Gunners defensively - you can't, because it is still the same players, regardless of who is in charge.

Chelsea are so inconsistent at the moment too. I watched their defeat by Southampton last time out and, as frustrating as they were in that game, I would not be surprised if they played much better here.

Lawro's prediction: 1-1

Mikel Arteta marks his first home game as Arsenal boss by making two changes to the side that started the 1-1 draw at Bournemouth on Thursday.

Calum Chambers, who was suspended for the last game, returns to the defence while French midfielder Matteo Guendouzi is also back.

Greece defender Sokratis Papastathopoulos and Switzerland midfielder Granit Xhaka are not involved in the 18, while 18-year-old forward Tyreece John-Jules is on the bench.

Arsenal XI: Leno, Maitland-Niles, Chambers, Luiz, Saka, Guendouzi, Torreira, Nelson, Ozil, Aubameyang, Lacazette.

Substitutes: Pepe, Mustafi, Martinez, Mavropanos, Willock, Smith-Rowe, John-Jules.

Frank Lampard reacts to last Thursday's 2-0 home defeat to Southampton by dropping England winger Callum Hudson-Odoi and midfielder Jorginho to the Chelsea bench.

There are recalls for Croatia midfielder Mateo Kovacic and England midfielder Mason Mount.

Nineteen-year-old defender Tariq Lamptey makes the bench.

Chelsea XI: Arrizabalaga, Rudiger, Zouma, Tomori, Azpilicueta, Kante, Kovacic, Emerson Palmieri, Willian, Mount, Abraham.

Substitutes: Christensen, Jorginho, Barkley, Caballero, Hudson-Odoi, Batshuayi, Lamptey.

Daniel Okeke: Saka, as a full back, in a London derby? Arsenal, is there any other better prerequisite for failure.

Bishop Yinkus: This is why it's not a good idea to have a favourite player. Pepe is on the bench again. Why? I'm desperate to see him getting some meaningful minutes on the pitch.

Gunner49coyg: My wish has been answered. Xhaka gone. We will see a big performance today.

OK, we are 10 minutes or so from the start of Arsenal v Chelsea.

The Blues remain in fourth, despite seemingly have been in on a pretty rotten run while the Gunners have been on a rotten run of sorts and are unsurprisingly down in 12th.

What will we learn about the two sides from this encounter? If anything.

Onlyravi: After a decade of ups and downs, title slips, and cup final defeats, the human moment after Liverpool came back against Barcelona and the whole team and staff sang You'll Never Walk Alone at the Kop End in unison still gives me goosebumps. It was this amazing team's defining moment.

• Arsenal could win consecutive Premier League home fixtures versus Chelsea for the first time since a run of three from 2001 to 2003.
• Chelsea's only victory in their past seven matches at Emirates Stadium in all competitions came in the Premier League in January 2016.
• The Gunners have never lost a Premier League home game against Chelsea when they've scored first (W11, D4).

Mikel Arteta needs to change the dynamic of the culture and build that team environment again. He talks about the connection with the fans, he stayed behind with the fans at full-time, he wants to bring the love back between the fans and team.

I'm not sure whether Mikel Arteta's comments after his first match in charge of Arsenal were merely encouraging, or slightly damning of his new team? Praising their efforts on one hand but saying their attitude was better than he expected on the other.

There were positive signs to build on though, and his first home game in charge brings a visit from an out-of-sorts Chelsea, who like Arsenal have lost their way lately.

The Gunners have won just one of the last 11 league games and find themselves in the bottom half of the table at the halfway stage, while Chelsea remain in the top four despite losing five of the last seven.
