They have been awful at set pieces, their marking is all over the place. Sterling was unmarked to tap in, how are City getting so many headers at goal? It's ridiculous. Dias did not even head it well - it hit him on the shoulder.

Two teams have ever conceded six goals in a Premier League game on Boxing Day. Well one team, because the other time it was Leicester too. They lost 6-1 to Arsenal in 2000.

Davinson Sanchez has a chance to get Tottenham's fourth. He is unmarked, near the penalty shot, but shows why he is a defender as he slices it wide.

The tempo has just been zapped out of this game.

David Moyes is encouraging from the sideline but it's starting to look like a first win in seven games for Ralph Hasenhuttl's side.

Still another 20 matches for Norwich after this and they're only three points from safety. But the Premier League's bottom club have been picked apart by an increasingly impressive Arsenal team. One minute plus stoppages left.

Will Crystal Palace go the whole match without a shot on target? It's Tottenham goalkeeper Hugo Lloris' 35th birthday today and it's been one of the easiest matches of his career.

Southampton are playing for time now. Tino Livramento is about to take a throw in but he is really taking his time.

Jan Bednarek hacks down Michail Antonio on the left flank and he's in the book for it.

Andy: Moyes will blame injuries after the game, but Dawson was hailed as one of our best players last season, Coufal is first choice, Masuaku very experienced, and Rice sat in front of them. There's more to it than injuries, something isn't right at the moment.

David Payn: To be fair, after last season's finish and the first three games of this season, people were entitled to question Arteta. That he's turned it round so quickly shows strength of character and not a little management ability

James Maddison gets a lengthy talking-to from the referee. It must have been dissent. He was booked earlier for kicking the ball away. Final warning you'd imagine.

Jarrod Bowen, who has been excellent today, squares a ball across the box but no one is on the end of it for the Hammers.

Michail Antonio tries to whip one in moments later but it's too deep and goes behind for a Southampton goal-kick.

Riyad Mahrez puts in an inswinging cross and with Raheem Sterling shaping up for a bicycle kick, Marc Albrighton heads behind.

Crystal Palace hand a debut to 21-year-old defender Nathan Ferguson, who comes on for Tyrick Mitchell, but everyone is just going through the motions. This game, barring an absolutely incredible comeback, has long been sorted.

Ozan Kabak on Alexandre Lacazette. VAR check complete. Lacazette to put the icing on the cake?

Southampton's Che Adams makes his return from injury as he comes on for Armando Broja, who has shown what a handful he can be again.

Said Benrahma is also coming off for the Hammers and is replaced by Andriy Yarmolenko.

Bukayo Saka appreciation post.

50 touches, 33 passes, 3 shots, 2 on target, 2 goals.

He's been quality today.

West Ham are working the ball well but they're going to have to do more than that.

Said Benrahma slices one from way outside the box and it goes high up into the terraces.

Arsenal are in cruise control. Mohamed Elneny and Nicolas Pepe have been sent on to make sure the Gunners see out the win.

Bukayo Saka won't be getting a hat-trick. He's given a standing ovation from the travelling fans as he makes his way off.

It should be 5-4. Luke Thomas flights in a cross which an unmarked Marc Albrighton heads wide at the back post.
