Let's start with cho should have started over mount. Cho is not good at tracking back,so you basically let james played against Robertson and mane 2v1 because of CHO. Just the sound of it make no sense.
2nd our fb did not push up high, have nothing to do with Lamp tactic. You want your fb high very2 simple, keep the ball high. We absolutely could not keep the ball. If the fb play high before the ball get to opp half, you may as well give salah and mane free pass to your goal.
Compare to last year, why we compete better it is simple. Against pressing willian and kova were our main way to get out from press, Kovacic did it multiple time on Sunday but that is it willian is gone. Can Werner do that? Nope. Havertz? Nope. Mount? Nope. So what other solution, wait till ziyech get healthy, long ball to Werner from Ziyech.
Lamp also said in his press that 2nd half we will have more attacking chances. This is true, no team can press hard for 90 minutes, so in 2nd half we will have more chances to attack them. Similar to our game in Anfield, we brought 3 fresh attacker late game and suddenly we were absolutely buzzing. But for Sundays once the red card happen, it was impossible to do that.
