Jordan Rhodes is expected to be named in Scotland's squad to take on Australia at Easter Road on August 15 after being left out of the Under-21 set up.
Fulham are thought to be eyeing a deal for the 22-year-old, who scored 40 goals for the Terriers last season.
And Scotland youth coach Billy Stark admitted his surprise that a deal had not already been struck for the former Ipswich man but insisted that the forward would remain loyal to the Galpharm Stadium.
Stark told reporters: "Last season will be difficult to repeat but in the previous two seasons he scored one in two, which is a fantastic average at any level.
"He is a goalscorer and a chance is a chance, and I don't have any doubts that if he gets a chance he will score in the Championship.
"You could maybe be a bit surprised he hasn't had a move after the season he has had. The window is open until August 31 so it still wouldn't surprise me.
"But he is such a grounded boy and he is not one who would be neglecting his work with Huddersfield waiting and wishing he was going to get a move to the English Premier League.
"He is looking forward to playing in the Championship."
