I am sure this has been raised before, but with defending more difficult in this iteration of FIFA this really needs to be addressed.
No matter what formation or instructions I use, and independently of the defensive work rate of the player concerned, defensive midfielders do not track back at any speed once the ball goes past them towards their own goal. Often, CDM’s just stand still and watch the play evolving behind them on the edge of the penalty area. At most, they may amble back to join the defence. The only way to get them to come back into the defensive third is to select them and run them back.
This is silly, and given the greater ability of attackers to keep the ball in Fifa21 it serves to unbalance the game. I am not suggesting the AI should defend on my behalf, simply that CDM’s should behave remotely like reality and actively seek to get into a position goal side of the ball once the ball goes behind them, rather than virtually standing still.
