Remarkable first half from Arsenal. It's difficult to gauge how good they were though because Crystal Palace were so dozy and never got started. Wilshere and Ozil have been good in midfield but the first three goals were so poor from Palace's point of view. They have been terrible in this first half.

Mesul Ozil - 11 - touched the ball six times in the build-up to Alexandre Lacazette's goal to make it 4-0.

Both goalkeepers have hardly had a save to make. United have dominated the ball and got into the final third but not worked the goalkeeper or the Burnley back four enough. It's very tight. Full credit to Burnley who have played well and certainly played a full part in the match so far. I think Jose will want more from his team in the second half.

In first-half injury-time, Anthony Martial, after a neat link-up with Paul Pogba, shoots wide.

But no shots on target from Manchester United in the opening half. Jose Mourinho will be demanding better in the second half.

Joe Wedgwood: Often losing a "star man" brings a team closer together and allows supposed lesser players to thrive. We don't need Sanchez! Backing Iwobi, Maitland-Niles, Wilshere, Ozil and Lacezette to excel big time!

Bruce Debenham: Jack Wilshere is definitely making a strong claim for a spot in the England team for Russia 2018.

Arsenal may have declared at four...

West Ham have had the better chances, but have not been able to find a way through. Goalless at London Stadium.

Head in hands, disbelief etched on the face of Xherdan Shaqiri. He thinks he's scored.

A ball over the top is nodded into his run, Terriers keeper Jonas Lossl looks to be in a poor position, no man's land but he actually does brilliantly in the end to throw up a right hand and claw away the forward's chip. Looked like 1-0 all the way.

Jamie Vardy's penalty the difference at the moment.

Sean Dyche has never been one to get too down about results. He will have been telling his players to keep doing what they're good at. People in this Burnley team know their jobs and do them expertly. They're really hard-working, organised and disciplined and his positivity will keep driving them forward.

Decent chance for Albion to double their lead and no surprises it comes from a corner - Salomon Rondon heads over. Wasteful.

Excellent play from the returning Ashley Young, making his first appearance of 2018. He picks up the ball on the left-flank, darts past Johann Berg Gudmundson and Phil Bardsley and curls an effort right-footed at the Burnley goal.

It would have been a stunning goal, but is just past the post, although it is better from the visitors.

James, Goodison: Stop the press, we've had a shot!

A first shot on target in 2018 for Sam Allardyce's side...

Sensational save! Wilfried Zaha gets a shot away on the edge of the area, it takes a deflection and is heading in until Petr Cech gets the very end of a finger tip to it. Superb stop, Cech is on 199 clean sheets in the Premier League.

Sam Allardyce and Alan Pardew are both on the edge of their technical area, both screaming at their players. It's a scrappy period of play.

Jamie Vardy has Leicester ahead, converting the penalty he won - that's the 13th Premier League penalty he has won in three seasons.

Manchester United have not quite found their cutting edge yet. They're probing but Burnley's back four have been compact and disciplined. It's going to be tough for United to break them down.
