Morrison has high hopes for the striker who has been a reformed character since a serious knee injury last term.
Scottish international Morrison, 27, admitted: "He was a bit big-time really. But he realised and has never looked back and been a modern professional.
"He has worked really hard, come back pre-season and lost a lot of weight and looked fit.
"He has been hungry to get in the first team and took his chance with two hands.
"When he gets a chance he will score. He is a threat on goal which is what we wanted.
"That is another goal and we hope he can get signed up. Maybe another goal is another few pounds to him.
"If he keeps doing what he is doing it will come to him. I am sure he will do well."
