The defence has to be controlled by the Ai to a certain extent. Yes his defenders should track back without him controlling them. What’s the alternative? He controls one defender and the other 9 outfield players just stand in one place, while you attack with the Ai controlling everyone in you team minus the ball holder. So it’s your 5 players running at his one defender?

If you were changing direction or doing skills and his Ai tracked you perfectly that would be an issue, but if you just run forward in a straight line at his defender what do you want them to do? If I’m defending and I switch player to track a run, and you dribble straight into one of my defenders then I expect them to tackle you. I don’t expect them to track you closely, I don’t expect them to anticipate skill moves, but if you walk straight at them they should tackle you.

You say that David luiz tackles upwards but he doesn’t have to move towards you. He stands in one place and tackles, again you run straight into him.

If you done a single fake shot or heel to heel you would have walked straight through his defence. But you can’t expect to have Ai assistance on offence and none on defence.
