Hard to be too disappointed with that.
Liverpool are better in every department so only sticking to a rigid gameplan was going to see Arsenal getting anything from it
As soon as Arsenal dropped their guard, Liverpool were going to find holes like a world class fighter. They're too experienced and too good to give any chink of light to. Thought Firmino's finish was pure class.
This will be a distant memory in 3 days if they beat Villa. If not, the other 2 games in hand away to Spurs and Chelsea will begin to weigh heavily.
Interesting to see how they react on Sat morning.
