I noticed this aswell, very unusual. Confidence completely shot too. Maybe not recovered after his peno miss in the summer?There was an action in the 2nd half (3-0 at the time) where he played a nothing ball into the midfield and they ended up having a shot from long-range that went wide. The camera panned to Akanji and he looked like he had the world on his shoulders. I don’t know what is wrong with him but he doesn’t look happy at all. Someone give him a maths exam to cheer him up.
Needs to be organising that defence much better when 3-1 up. Forgive the first goal. Then make sure you are shouting at everyone and marshalling them. You are the senior pro that's your job. If a midfielder isn't tight bollock them. If your offside line isn't right, shout it from the rooftops so the players get in position.
And if you lose the ball bust your gut to get back rather than jog.
Assuming that you are fully fit that is .
