Deep into the three minutes of injury time and it looks like Arsenal have done enough - but only just - to take all three points as West Brom are out of ideas.

Arsenal have the ball at the right end of the pitch as far as they are concerned and look comfortable playing out the final moments for an opening day three points - but it has been promising from the Baggies.

West Brom are still in with a chance here if they can just force an opening for the likes of Bednar - but at the other end van Persie turns and almost finishes things off brilliantly but the ball drifts wide.

Adebayor is a man whom the fans have rather fallen out with over the summer after his public flirting with Milan and, as he runs down a blind alley, he is actually booed by a section of supporters.

Smart, but rather ponderous, play from Arsenal down the left flank again as Adebayor eventually wriggles free to stand the ball up to the back post where Van Persie rises to head straight at Carson - his first save of the half.

With West Brom pressing for a priceless equaliser they are opening up gaps for Arsenal to break into from deep and that is arguably where the hosts are at their most threatening.

Suddenly everything has become a little tense inside the Emirates as West Brom start to look dangerous once more and the Gunners' frustrations are growing.

Adebayor is the second player to have a goal disallowed for offside as he tucks home Walccott's cross from close range but after a fortuitous ricochet it is no surprise Walcott was offside in the build up.

Emmanuel Eboue is lining up another attempt fron range but he rather sums up why he frustrates so many of the home supporters on such a regular basis as he slices it well wide.

Theo Walcott thinks he is about to give Arsenal a two-goal cushion but James Morrison makes a timely sliding challenge to divert the ball away from the England winger.

Robin Van Persie has been lining up ever since the start of the second half and you get the feeling it might not be long before the Dutchman makes an appearance to try and spark Arsenal back into life.

Ishmael Miller blasts the ball into the back of the net but he had not quite managed to get himself back onside and referee Webb was quick to disallow it.

A slight lull again at the moment but West Brom have made a game of this, something that looked almost impossible in the opening ten minutes.

Just like that! Glorious chance for Adebayor as he is fed into the left channel and attempts an Henryesque finish inside the far post but he doesn't quite bend it enough as it slides wide.

Almunia and Gallas are screaming at each other after that and suddenly the lead looks fragile - alternatively it could fire the Gunners up.

Oh so close for the visitors! Miller eludes all his markers to find himself through on Almunia who makes a superb save and then as Robinson drives the rebound goalwards Djourou is on the line to deflect it wide.

A slow start to the half with the Baggies looking a lot more settled than they did first time around and Arsenal are content to pass the ball about and be patient.

It appears Arsenal are going to have a burst for a second goal in the final moments before the break but Adebayor is crowded out on the edge of the box this time.

Samir Nasri has been a little quiet in the last quarter of an hour bt he bursts back into life with a sharp left footed effort from range that is too hot for Carson to handle at the first attempt.

West Brom have responded very well having gone behind so early in the game and need to hold out until the break now if they can to really build a base.

Arsenal are just starting to wind themselves up for a further assault on Scott Carson's goal as we approach the end of the half and Eboue fires wide.

Route One from West Brom and almost one-one on the scoreboard as Kim's left footed bobbling effort forces Almunia to parry the ball wide.

Chris Brunt is usually very reliable with his left footed delivery but not this time as he drops a corner into Adebayor at the near post and then floats the second chance over everyone.

Shocking marking, shocking miss! Bendtner is left inexplicably free on the edge of the six-yard box to meet Nasri's corner but he mistimes his header and wastes the chance.

A little aside here by the way that the opening 20 minutes have not seen any problems with the new 'RESPECT' intiative - although admittedly there has not been a tackle or incident of any note.

However, Arsenal are still thoroughly enjoying themselves in the opening stages here and Bacary Sagna hits a half volley with his unfavoured left foot that skews of Leon Barnett just wide of the far post with Carson stranded.

Better from West Brom. Greening, Kim and Cech are beginning to find some time on the ball themselves and just slow down the tempo a little.

Tony Mowbray is out on the touchline frantically trying to organise his side a little better because at the moment the Gunners are in cruise control.

That rather typifies it! William Gallas waltzes gently into midfield to pick up the ball and drive it from all of 30 yards and its just a matter of inches wide of the post.

You simply cannot give Arsenal this much time and space on the ball but West Brom are not getting near them - they need to get tighter and more in their faces before things get worse.

The signs are worrying for West Brom early on here because Arsenal's passing is in the groove already and Adebayor crosses for Walcot and thankfully for the Baggies Robinson is in the way.

There were concerns before kick-off that Arsenal were lacking a ball winner in midfield and Emmanuel Eboue is the man given the responsibility of denying West Brom space in midfield.
