There could be a few of the younger players that potentially make a move to get game time, but Gallagher, who spent all of last season at Birmingham, isn't likely to be among them.
Hughes said: “Sam is very much in our 25.
“We get a lot of interest in Sam I have to say. It's understandable if I'm honest having worked with him for the first time.
“He has a lot of attributes. He is a strong young man, a lot of talent, a lot of pace and you can see why clubs would like to take him on board and work with him this season.
“He's not one we are encouraging any clubs to come for."
