Feedback resistant direct

Hi,

I have a direct who is happy to attend 03s, however he cannot cope wih any form of critica feedback and is not good with positive either.

He doesn't hear what I have said he just becomes withdrawn and if I keep pushig depressed. (I have been working it him for seven years and have tried many approaches)

He desn't seem to undestand positive feeback whenever I give it he looks confused, it also seems to have no affect in changing behaviour.

I think he has Aspergers as we all did a online test and he came very high on the scale (However he des not accept this)

He has a tendancy to procrastinate on projects. (aim, aim, aim ..) his coworkers find this and is lack of focus on one project at a time very frustrating.

When challeged he will misdirect and somtimes outright lie to deflect feedback.

He cannot cope with confrontation but is very conrontational.

He can do his job - when on task.

He is a small team leader (3)  which he is very poor but does not want to give the roll up.(He thinks he could manage production). He is the poduction support team leader and does not communicate well with the rest of producton and wants to be involved in everything.

HELP - I have totally run out of ideas.
