Given all that he's been through and appears to still be going through there should be an open door policy for Jack to train with us for as long as he wants.
Realistically you couldn't justify signing him as a player at this stage even on a free, though I'd still kind of love it if we did.
If he's looking at hanging up his boots fairly soon he should have some kind of ambassadorial job here. Got to look after him.
Emotionally it's hard to let go of players like Jack. With the talent he had he deserved so much more out of his career.
