Please read my post again, I explained the reason why Walker should have have hung back. This kind of brainfart where we gift the ball to the oppo in front of the box happens time and time again so surely it's time we learnt our lesson?
That is not how we play .. not my opinion, Poch style
I sat and watched open training less than two weeks ago, where we did a half field drill, pass out from Keeper -> CB -> CM -> FB, rinse and repeat. The drill ended when the FB got the ball in full flight at half line or further. In this specific play, Walker was actually the deeper of the two (Davies was even higher up as furthest forward option), it's only Walker's crazy pace that even allowed him to get back.
This is the reason many people have argued for a dedicated DM or a Carrick/Modric type controlling the center, because the way we play, leaves the FBs too high up the pitch.
What you are effectively saying is Poch has no idea what he is doing, Walker should understand that, ignore orders and provide cover for the brick style Poch wants to implement.
