This was a classic 'bad' 4-4-2 game. Players just going through the motions, flat banks of 4, pass it horizontally, cross when there are 3 defenders covering your strikers. If the red card hasn't been there, 99% a 0-0 game. In fact, the red card probably gave us our best chance of getting something out of this - in case Bologna smelled a win (as they did) and came forward, we could have had a couple of good counters.
You cannot play 4-4-2 in modern football without at least one midfielder or a fullback moving incisively towards the box. Not a single person did that last night. This isn't an unknown concept obviously as Kessie has done that plenty of times for Milan in a 4-4-2. So clearly, everything went wrong.
