Liverpools defending is shocking, how the defensive coach is still in a job there is a puzzle. They need two decent centre halves as the ones that they played were complete rubbish. Nobody seems to be able to head a ball in defense.
The City match told us nothing really, other than Peps formation makes them mostly very narrow and easy to defend against. Both wingbacks like to cut in, so the defense can stay tight in the middle (in the case of Brighton 6 at the back with two just in front).
