Just had a quick google, apparently he’s with Stellar football ltd who also have this bloke called Gareth Bale on their books.

He’s recently been in the best form of his short career but somehow you still manage to have a dig at the manager/coaches who have gotten him to this point... what he used to do was stand still, high up the pitch, and wait for the ball. Now he moves around and looks for the ball because he now understands that staying in the same place and waiting makes him nice and easy to mark. They must have made his new shackles out of titanium so that he can move more freely in them..
McParland is right that Jack's dad is his agent. His Dad and family are villa mad so it would take something extra special for him leaving villa park to happen. Rest easier over Jack. Jack's agent is one of us and it's not about money there
