I guess we're going with a 4-2-3-1, but without a cm playing out with in the three, like Milner often does. I worry as a result that we'll be a little overrun in the middle, the emphasis will be on Lallana and Firmino to drop into the midfield as needs be.
Believe Klopp mentioned controlling their flanks. The 3 AM should take turns to pressure the flanks while the 2 DMs stifle the middle and provide more backup to the fullbacks. We will spring into attack once the ball is won, it's looking that fluid.
