Lambert believes it is easy to forget how meteoric Morison's rise is after plying his trade in non league only a few years earlier.
"I think he is getting better with every passing game," he told the Pink'Un. "For someone who has just come out of non league two years ago or whatever it was it has been a huge rise in his own career. He has a long way to go but he is doing really well. I think the thing is it's his work rate that is deceptive. When the ball is played up to him he is a handful the lad.
"It's a brilliant story for him. The way Morison has been playing now he has been excellent for a number of weeks."
