I am not ITK. I understand i'll get pelters for this but thought i'd share.
A colleague of mine is friends with someone, who has another friend, who allegedly knows the grealish family well. According to them, his family are distraught that jack is going and have apparently been in contact all day with jack trying to get him to reconsider. That's why the deal hasn't been finalised today.
Personally think its all bollocks but just passing on info.
