Liverpool were abject for the first 20, 25 minutes against Arsenal. The Gunners have not been involved in one of those games this season. Liverpool are practically impossible to face on the pitch as Ian says. But when they do find themselves and move into that phase, they are absolutely irresistible. It was like it just genuinely became a completely different game. They must have known what was going on where these players were five minutes ago. If they could find themselves five minutes before kickoff, that'd be great - but they don't.
