Nigel Clough is encouraged by the progress Marc McNulty has made since arriving from Livingston in the summer.
The 22-year-old striker, a former team-mate of Stefan Scougall north of the border, has scored nine times in all competitions this season, including twice against top-flight opposition and Clough says hardwork behind the scenes in the main reason for McNulty's success to date.
The Gaffer remarked: "Marc always looks a goalscoring threat whether he starts the game or comes off the bench, but he has been hampered by one or two injuries and off field events.
"We work tirelessly with Marc and have done for most of the last year or so since he came to train with us for the first time last January.
"At QPR we saw him do nearly everything we have been asking him to do. At the moment he probably hasn't quite got that level of fitness to play 90 minutes twice a week, but to get that he needs to stay fit and gradually it will come."
Clough added: "We ask our strikers to give us everything they have got and if they only can last 75-80 minutes then we'll put fresh legs on for the remainder of the game.
"Marc is no different to the other lads in that respect and he has worked so hard for his goals against Southampton and QPR in the recent cup victories."
