Interesting, I assume that you had the "Follow Depth Chart" option active for this match. Also, did you leave the backup and reserve positions for your Center blank, or did you have Zhidkikh assigned to all three?
I have also sometimes had the case that even when done everything right, the manager substitutes younger players off for a short time in a game. I have had the feeling that the GE recognizes that they need less minutes for training ans thus get some minutes off of them on purpose. But for me it has only happened irregularly a couple of times, so I do not know what the real explanation for this situation could be.
