Naismith told the Observer: "He's trained with the first team quite a bit since I came here.
"The right folk are here at the club to help him mature and not rush him through things. His all-round game and touch is excellent. He's not the biggest of boys, but he can hold his own when the defenders are closing in on him.
"He is doing tremendously well and long may it continue. He's in at the deep end, but he's not out his depth. Some days he's doing everything, scoring goals, playing passes and it's great to see. It's good experience for him right now being about the first team."
