Hello and welcome to our LIVE coverage from the Emirates Stadium where Arsenal welcome West Brom in the Premier League.

West Brom get the second half started, with what I can only assume is a feeling of ominous foreboding.

Right, I wonder what on earth this half holds for us.

Half-time. Well, that was eventful.

And Wilshere attempts to grab another goal before half-time, but he can't quite control it in his stride and it balloons over the top.

Two minutes of additional time.

Ospina notices the deflection as Morrison takes it, and gathers it well.

Grumbling around the Emirates as West Brom win a free kick after Gibbs fouls Morrison.

Good save from Myhill there, tipping Walcott's shot around the post.

This really is some lovely football from Arsenal today. West Brom fans already leaving their seats. Can't really blame them.

Tony Pulis is slumped in his chair. He'll have to give one heck of a half-time team talk to get anything from this.

It's a straightforward enough tap-in for him, but smart work from Walcott and more great approach play - it's a cross from Wilshere as well, mark you.

GOAL! It's Theo Walcott's hat-trick!

Meanwhile, Coquelin takes a Dawson arm to the face as he attempts to brush him off.

Some pacy Arsenal play here, with Walcott seeking out Sanchez this time, but his shot is blocked.
