His decision making is fine. The problem is that the agenda is so strong against him everything he does is put under a microscope and over analyzed to death in order to find ways to blame him
Its not really. Not at all. If you watch the games you can see that he choses the wrong option 7 out of 10 times. I will list a few
1. Heading balls back into no mans land for no reason whatsoever. Without being pressured if i may add
2. Rushing into players for no reason.
3. Getting in the way of other defenders.
4. Holding the ball for way too long on his feet.
5. Not having the self realization that he is slow and can be turned over by a someone with an ounce of pace but still being out of position.
6. Zero command over the defensive setup. As a leader and main CB he needs to communicate with other defenders.
7. Misses more headers than connect in his own penalty box
8. Delayed responses inside the box
I can go on but you get the point. Like i said he is a decent defender but not good enough for United. Unless he decides to correct his weakness
