LAST MEETING
September 25: Arsenal 2-3 West Bromwich Albion
Goals from Peter Odemwingie, Gonzalo Jara and Jerome Thomas handed Arsenal a shock first league defeat of the season.
PROBABLE LINE-UPS
West Brom: Carson; Reid, Olsson, Meite, Shorey; Brunt, Morrison, Mulumbu, Reid, Thomas; Odemwingie.
Arsenal: Almunia; Sagna, Squillaci, Koscielny, Clichy; Wilshere, Denilson, Ramsey; Nasri, Van Persie, Bendtner.
Prediction
With both sides desperate for the win and with doubts in defence, there should be goals galore at The Hawthorns. Arsenal's superior attack should see them edge a helter-skelter contest.
West Bromwich 2-3 Arsenal
