For some reason I think Liverpool is going to win. They have already beat Manchester United and Chelsea this year. I know they haven't won at Arsenal in a long time but they already ruined Chelsea's long home winning streak this year. I think this is going to end another streak.
Outside of when Arsenal beat Man U a few weeks back they have been in terrible form and have quite a few injuries.
I see value at Liverpool at +215 and I plan on laying a unit or two on them.
