Birmingham boss Hughton knows Arsenal, Man Utd keen on Butland
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 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."
