George Baldock wins a free-kick when he's shoved over by Robert Snodgrass. It's another decent position for United. Can they do better this time?

Wolves are looking for an immediate response. Daniel Podence thinks he's won a corner but he has to settle for a throw-in.

It's then played down the line for Pedro Neto, who manages to squeeze a cross in, but he can't find Willian Jose in the middle.

Ethan Ampadu does well to get a shot away before it comes out to John Fleck on the left.

United have a corner but it's punched away at the near post.

It's been coming...

Sam Allardyce is absolutely livid on the touchline after it's given away on the left. West Brom do win it back eventually but Kyle Bartley then fouls Billy Sharp.

Bukayo Saka goes down under contact from Willy Boly. There's strong appeals from the players who think the referee has given a penalty but eventually he points to the corner flag. That was a bit confusing? Didn't look like much.

Sheffield United deal with a ball in from Jake Livermore and they try to counter. John Fleck has time and space, before moving it left.

The cross doesn't come in early enough and it's back with West Brom.

Relentless from Arsenal.

Emile Smith Rowe, to Hector Bellerin and into the middle. It's away by Willy Boly and out of reach of Alexandre Lacazette.

Max Kilman has got himself a yellow for a foul on Bukayo Saka in the build-up too. Corner to Arsenal.

Arsenal could be 3-0 up by now.

Nicolas Pepe comes onto it after another slick move down the left. It's cut back into the middle and he hits it first time but it smacks off the keeper and onto the crossbar!

Dara O'Shea launches a big throw in from the right but Semi Ajayi is penalised for a push in the box.

Nelson Semedo hits it from long range and it almost catches Bernd Leno out. It skids across the wet surface and the Arsenal keeper spills it initially before gobbling it up.

Luke: Shame no goal for that brilliant finish. But Saka is easily among the first names on the teamsheet for England going forward.

Adama Traore skips past a few challenges in the middle and lays it off to Pedro Neto on the left.

Again, Hector Bellerin is there to make the clearance.

It's just started to settle down a bit. West Brom started very brightly but Sheffield United are getting a lot more of the ball now.

Pedro Neto almost manages to squeeze it in from the left but it's out for a corner by Hector Bellerin.

Mr Makoaba: Honestly I've never understood Wolves' insistence on playing a back three. They have a good enough squad to play modern football.

Daddy M&N: What happened to Wolves? And maybe Sheff Utd? Two teams fighting for European football last season are now trying to avoid relegation.

Gil Lau: Saka MOTM inside four minutes.

Callum Robinson is furious because he comes racing over to make a tackle near the touchline as West Brom head away a corner.

He thinks he wins it and it goes off David McGoldrick but the throw-in goes Sheffield United's way.

Bukayo Saka. He's everywhere. Wolves can't handle him!

Again, he's in behind on the right. He cuts it back, beating Max Kilman, then slips it inside for Nicolas Pepe, who misses it by inches.

He's offside anyway but Saka is having a lot of fun.

That’s one of the clearer decisions.

When I first watched it, I thought Lacazette had timed his run perfectly but that’s the beauty of VAR – when it’s crystal clear like that and we’re not looking at millimetres and toenails then we can stand by that decision quite comfortably.

But what a start from Arsenal.
