You think he should be challenging the man further away from the goal?
Blind is the LB. Bergwign the LW.
Trent's man and the most dangerous player in this scenario is the LW (as he's closer to the centre of the goal).
I was very critical of Trent last week, and generally he's been shocking defensively and effort-wise lately, but this situation is the fault of others. Thiago lost the ball and recovered slowly, Kostas and Trent were out of position (thinking we had possession), VVD and Matip are marking the same man. TAA is then left with 2 at the back post.
