Quite possibly the fairest outcome from this fixture. Sanchez's free-kick was deflected into the net by McClean late on before Rodriguez scored from the spot in the final game of 2017.
93'
Arsenal desperately looking for an equaliser. Sanchez fires wide from 25 yards.
Koscielny replaced by Mertesacker. Krychowiak on for Brunt.
66'
Arsenal's latest flurry of chances still not enough to find the back of the net and West Brom are still a threat on the break.
63'
Sanchez cuts in from the left but his effort hits the side-netting.
62'
Lacazette close again! The Frenchman almost pokes it past Foster who was in no man's land. Just wide.
60'
Rain starts to fall heavier now with the hosts throwing some testing balls into the Arsenal area.
59'
Great passing from Arsenal and Lacazette's low shot from inside the box is kicked away by Foster.
58'
Brunt booked for a tackle on Wilshere.
53'
Arsenal passing the ball around but it's predictable and easy to deal with for the Baggies.
49'
Lacazette is brought down at the edge of the box. Good position for Sanchez, but it hits the wall.
48'
Arsenal need to step it up after a rather pedestrian first half. The Baggies could get the boost they are looking for with a win to lift them from the bottom of the table.
46'
We're back underway. Arsenal have possession.
45'
Still no goals here. Arsenal have seen more of the ball but chances have come at a premium with the hosts defending well at the back. Will we see a goal after the break?
45'
2 added minutes.
42'
In the 42 minute, a standing ovation for Richard Eades, who was the Baggie bird mascot at the club and passed away on Boxing Day at the age of 42.
42'
Arsenal are looking for an opening through the centre of the West Brom defence but it's far too congested. Wilshere almost manages to pass Lacazette through.
40'
Half-time approaches and it's a rather subdued atmosphere here. Both sides have closed down after an open start.
The hosts are doing a good job going forward and Rodriguez has been lively but neither keeper has been truly tested yet.
21'
An open start to the game with both sides finding space in the final third. West Brom win another corner and the home supporters come to life.
15'
Good spell of passing from Arsenal and Iwobi is allowed to turn at the edge of the box. His curling effort whistles just over the bar.
10'
A decent start to the game with both teams looking for an early opening.

Arsenal at the other end now. Lacazette finds some space but his shot is deflected for a corner.
6'
First opening for the hosts with Rodriguez heading the ball towards goal but Cech is equal to it.

We're underway! Mike Dean the man in the middle.
