The 27-year-old scored his first Premier League goal in two years, in the 1-1 draw.
“It’s going to give him massive confidence. It’s a long time since he has actually stuck one away,” said Kinnear.
“But I believe he has got all the ability to make himself a decent striker.
“He has got power, pace, strength. He has possibly not been punching his weight in the past, I don’t know really.
“I can only go on what I see, and he has been exceptionally good for me in training.
“He has sent out all the right messages. He is a hungry fighter.”
