I feel a bit sorry for Justin as it seems to me that he is being criticised for fulfilling the role that Cooper has given him.
I'm not a football hipster, so correct me if I'm wrong, but in possession, Cooper asks Justin to sit in with the two centre halves to form a three. For that reason, he is likely preferred to Ricardo. Then he gets criticised for not coming forward and also criticised for being to narrow.
Meanwhile, with Justin sitting, Kristiansen is given licence to push forward and join the attack with the left winger drifting in field.
I don't really understand why we don't allow either full back to push forward, depending on which flank we are attacking, while the other one sits. I would then play Ricardo as rb and Justin lb.
