- Arsenal fall to seventh in the Premier League table after goalless draw in east London.
- Javier Hernandez hit the cross bar in the dying minutes for West Ham.
- A point sees the Hammers remain second from bottom.
- Olivier Giroud frustrated in what was his first start in the league this season.
West Ham's improvement continues; they will remain second from bottom tonight but they will take plenty of positives after showing plenty of grit and resilience against Arsenal tonight.
With Liverpool and Tottenham both winning tonight, the Gunners have fallen to seventh. Their frustrations on the road continue.
Full-time: West Ham United 0-0 Arsenal
Ozil's effort clips the wall and goes out for a corner but that will be it!
Ooooh, Arsenal will have a free kick in what will probably be the last kick of the game. Reid committed the foul, but it was prompted by an error from Zabaleta. Ozil will lift this into the box...
Amid all that, two minutes of time were added on.
West Ham almost snatch it at the end! Bellerin plays a horrible pass across the face of his own goal, causing panic at the back. Noble picks up the pieces after a poor clearance and slides a superb ball through for Hernandez who gets the ball onto his right foot and curls one on goal. He thinks it is in. Moyes on the touchline thinks it is in. Cech probably thinks it is in. But his effort comes back off the underside of the bar!
West Ham get a chance to catch their breath with Bellerin over-committing and conceding a foul.
And here's another change for Arsenal, Sanchez's evening is brought to an end with Alexandre Lacazette onto replace him.
Here comes Javier Hernandez, he is onto replace the slightly knackered-looking Antonio.
Ogbonna has been excellent tonight; this time he takes on Welbeck one-on-one, reading the Arsenal man's attempts to jink past him before confidently taking the ball away.
There is a sense of inevitability to Arsenal scoring here; West Ham just can't clear out of their own half and Arsenal are coming at them strong every time.
Just over 10 minutes remaining in this contest.
West Ham are constantly giving the ball away at the moment as they try and relieve some of the pressure Arsenal are applying. They need a breather.
Adrian produces the save! Sanchez guides a fine, dipping effort over the wall but Adrian follows it all the way and palms clear.
WIlshere plays a tidy ball around the corner but is caught late by Noble. Arsenal have a free kick in a fantastic position about 30 yards out from goal.
Here's Arsenal's first change of the evening with Danny Welbeck on for Iwobi.
What a chance for Wilshere! Again, Maitland-Niles does terrifically out on the left, lifting another beauty of a cross into the six yard area towards Giroud. The Frenchman opts to nod it down to Wilshere rather than aim towards one towards goal, but under pressure from Ogbonna, the England international lifts his effort clean over the bar.
Cech's blushes spared! He comes out to punch a cross and makes an awful mess of it, missing it completely with Arnautovic on the scene. He tries to scramble the ball over the line with Monreal managing to hook it clear first but the whistle goes for an Arsenal free kick - seemingly for a slight push on Koscielny from Arnautovic.
Iwobi tries to measure a pass down the inside right channel for Sanchez to get onto but Ogbonna gets across to take control of the situation. Arsenal had been ramping up the pressure on the West Ham goal earlier on in this half but it has faded in the last five minutes or so. Maybe it is time for Arsene to freshen things up a bit up front...
Alexandre Lacazette is stepping up his warm up. Might not be long before we see him introduced.
Another chance passes Arsenal by! The ball takes a lucky bounce into the path of Ozil after some more neat two-touch passing, but he flicks his effort from about 10 yards out across the face of goal and out. Poor effort.
Close from Giroud! Maitland-Niles again does well on the left, cutting in onto his right foot and clipping a cross into Giroud who looks to nod one just inside the near post. His effort takes a slight nick off his marker and goes out for a corner.
Iwobi and Groud combine elegantly in the box but West Ham just survive with Ogbonna prodding the ball out of the latter's path.. The ball breaks kindly to Xhaka about 25 yards out from goal and he tries to guide one into the top corner. It's a sweetly struck strike, but an easy save for Adrian in the end.
It's been a much brighter start to the second half from Arsenal, they are moving the ball around slickly in the final third but West Ham are proving to be a tough nut to crack.
