Some really silly comments on here. It is not the same situation as Tom Davies. Shackleton is under contract.
Due to his injuries nobody is going to sign him.
He is our player next season. We can either pay him up (not cost effective as we’d need another player in too so you’re paying two wages for one player), loan him out (and wpuld probably only get a small % of his wages covered), or big him up, get him fit and see if he can be our back up right back, something we don’t have.
Regardless of what happens we are paying his wages for another season, therefore we may as well get him as fit as possible to get some games out of him, especially as money will be tight next season.
