Well they can sack him then.Celtc are in a rather invidious position with him.
They can't sack him as he wasn't charged (huge difference than being found innocent as some tinks are saying).
They can't play him as he'll cause riots in his own crowd and the opposition fans ,at every club, will hound him.
They can't sell him as no club will want to be associated with a nonce.
All they can do is keep him in the books until his contract is up.
As you say, he wasn't charged.
It doesn't mean his social media won't have brought the company name into disrepute.
Unless that company already has a reputation for paedophilia, of course.
