Brum boss Chris Hughton admits they face a battle to keep hold of the youngster.
"I understand all the speculation about him, and you only get that if you are a talent," said Hughton.
"Jack is a really young and a very good talent. But the three young players who have been very much part of our squad, including Nathan Redmond and Jordan Mutch, are at the best place.
"Jack has been given the opportunity to go out on loan. We could have kept him here and looked after ourselves, but we made a decision for his development and are delighted to have him back."
