Your club-branded Bet Butler site not only gives you the best odds from more than 60 bookmakers, but every bet you place there benefits the Baggies!
Albion are 16/5 underdogs to beat the 19/20 Gunners, or you may fancy the draw at 11/4.
Alternatively, if your feeling confident, why not back the Baggies to win 2-0 at 20/1.
Elsewhere, fans of the Barclays Premier League will have to wait until Monday night for the Manchester derby, where United are 6/5 favourites to overcome 23/10 City, and all but seal the title.
You could also back the draw at 13/5.
If you can’t wait until Monday, why not back Nigel Adkins' Reading (11/5) to beat former club Southampton (6/5) in the lunchtime kick-off.
Villa (14/5) head to Stoke (11/10) hoping to drag their hosts into the mire and, on Sunday, Tottenham (17/20) entertain Everton (16/5) with both sides battling it out for a place in next year's UEFA Champions League.
Now you can back Albion during all the big matches too, as in-play betting is now available at wba.betbutler.co.uk
