Michy Batshuayi comes on for Jordan Ayew up front for Palace. Can Palace see this out? Not that that's a change with seeing things out in mind.

David de Gea has failed to save the last 18 penalties that he has faced in the Premier League (because that one doesn't count), last saving one from the spot in October 2014 against Everton.

Don't add Gareth Bale to your fantasy football teams yet.

Spurs have confirmed he will not be fit to make his debut until after the international break next month. He suffered a knee injury on Wales duty last time.

They have also announced he will wear the number nine shirt.

Macca10: LFC fan here and that Palace penalty is a disgrace. Defenders can’t have arms if we are giving penalties for that. Ridiculous..

Stavros Makro: ....and when the enemies of football decided to destroy football they invented VAR.

Arsenal boss Mikel Arteta makes two tweaks to the side that won 3-0 at Fulham in their Premier League opener.

Bukayo Saka and Dani Ceballos both start which means Mohamed Elneny and Ainsley Maitland-niles drop to the bench. Defender David Luiz who has been passed fit following neck spasms takes a spot on the bench.

Arsenal XI: Leno, Bellerin, Holding, Gabriel, Tierney, Saka, Xhaka, Ceballos, Willian, Lacazette, Aubameyang.

Subs: Macey, Maitland-Niles, Pepe, Luiz, Elneny, Nketiah, Kolasinac

Subs: Randolph, Balbuena, Yarmolenko, Anderson, Lanzini, Haller, Johnson

Gary Neville is furious on the Sky commentary - both at the penalty award in the first place and then at the retake.

That decision may be controversial but it is absolutely in line with how the Premier League have been told to apply the law by Fifa this season.

The keeper has to have a foot on the line - on the ground - otherwise the spot kick gets taken again.

Play had continued. But Palace get a retake because De Gea was off his line...

David de Gea saves! Jordan Ayew strolls up so casually and just tries to stroke the ball into the bottom corner, but De Gea saves.

Martin Atkinson gives the penalty. Victor Lindelof's arm was in front of him but it was only a couple of inches away from Jordan Ayew's shot. Harsh?

This has not been very good at all by Manchester United.

Now it is new signing Donny van der Beek's turn to make his debut.

In fairness, Paul Pogba has been disappointing - but it could have been anyone.

Man Utd 0-1 Crystal Palace

Oh well now. It hit Victor Lindelof's arm and the referee goes over to the VAR screen to have a look and see if this is a Palace penalty.

End to end. Jordan Ayew goes forward for Palace and he tries a spooned chip, but it's blocked by Victor Lindelof and David de Gea catches.

A big chance for United as Scott McTominay flicks on a corner to Victor Lindelof, who puts it over from six yards.

On comes £35m summer signing Donny van de Beek for United. Paul Pogba comes off.

Wilfried Zaha has the ball in the back of the net - but it won't count. Jordan Ayew steps past a defender and then slips the ball through to Zaha who rifles the ball into the roof of the net.

We get these late offside decisions now so the flag goes up after the goal. It was a clear offside really.
