Hello and welcome to our live coverage from the Hawthorns.

Arsenal are winless in the previous 10 Premier League matches they have trailed at half time (D3-L7). Not since they came back from 2-1 down at the break to win 5-3 at Chelsea in October 2011 have they reversed a half time Premier League deficit to win.

It was Berahino who came up with a glorious ball that Anelka couldn't take advantage of.

Wilshere denied a clear penalty. Wallops the shot over, but clearly taken out of the action late by Jones. Bad decision by the referee. Or non-decision.

Glorious chance for Anelka to add a second for the home side, but he can't convert in front of goal. Should have been a second for West Brom.

Arsenal get the second half off and running then.

There goes the whistle for the break! A 1-0 lead for West Brom. Work to be done by Arsenal in the second period.

Wilshere with a bad tackle on Jacob, who is in need of some treatment. A booking for his challenge on the goalscorer.

We are into three minutes of time added on.

West Brom last beat Manchester United and Arsenal in the same top flight season in 1983/84, winning 1-0 at Highbury in December 1983 and beating Man United 2-0 at home in March 1984

Arteta with a clearance seconds later that is none too convincing. West Brom suddenly with a purpose about their play.

West Brom have not done too much in this contest, but they hold the lead. What have Arsenal got in reserve? Test of character now.

GOAL! Yacob arrives to head into the net from the Morgan Amalfitano cross. Brilliant delivery and finish. West Brom lead 1-0.

Better attack from the home side ends up with Stephane Sessegnon seeing a volley blocked by Per Mertesacker.

Ozil's corner comes out to Ramsey, whose shot from distance is brilliantly parried clear by the diving Myhill. Superb stop from him.

Gibbs looking to test the home defence, but his cross is blocked for a corner.

Wilshere claiming he was taken out of the game late by Olsson, but he appeared to run straight into the West Brom defender.

West Brom toiling to cut open this Arsenal defence, but the visiting side not exactly wallowing in chances either.

Laurent Koscielny seemed to take out Mulumbu with a late tackle, but the referee said no.

Mathieu Flamini receives his fourth Premier League yellow card this season, the joint-most with Lucas Leiva (Liverpool). Of his four league red cards, none have been in the Premier League (three in Serie A, 1 in Ligue 1).

Wilshere rejoins the play for the visiitng side as Ridgewell knocks a long pass straight out of play from deep.

Of West Brom's six Premier Leagues this season, two have been scored by English players. Last season only one of their 50 Premier League (exluding own goals) was scored by an English player (Billy Jones v Newcastle).
