I disagree, I don't think this Liverpool team know how to play defensively. Which isn't praise! It's why that was the only clean sheet of the season and it'll be why there'll definitely be no title this year. Klopp always seeks to play the team to their own strengths rather than adapt to the opposition's weaknesses, similar to Monsieur Wenger.
In the game itself, Liverpool had two thirds of possession, more shots (off and on target), more corners and less fouls, all of which points to a much more attacking display. Liverpool didn't do much in the first half an hour because they were just trout and couldn't even string two passes together - it wasn't for a lack of intention, just a lack of application. Of course, you can also credit United's pressing of both players and the goalkeeper for the inability to retain possession and build from the back. Regardless, it certainly was not a 10 men behind the ball thing a la Mourinho.
