"I think at the moment he is our form player," Allardyce told the Rovers website. "With his assists and the goals he has scored himself he is right up there and his overall performances are looking very good now.
"With a little bit more luck he would have had more than one goal against Wigan when his header hit the bar.
"He showed terrific attitude to try and score the goal even though it meant putting his head in where it hurts and that is very important. That showed he was prepared to get a whack in order to try and score a goal.
"Morten is an experienced player for us and he can be our match winner by turning a game in our favour, as he did against Wigan. I hope it continues."
