Carlisle manager Keith Curle says loan signing Georg Iliev cannot be judged fairly after the service he received in Saturday's defeat by Plymouth.
Bolton striker Iliev, 19, made his debut as the Cumbrians' three-game winning run ended at Home Park.
"The centre forwards are only as good as the service they get," Curle told BBC Radio Cumbria.
"You can make fantastic runs but if you don't get the delivery at the right time it doesn't look pleasing."
The game was the first time in six matches Carlisle had failed to score but Curle is confident their touch will return.
"I know what Georg is about, if we get chances in and around the box, he'll hit the target," Curle said.
Iliev's move was confirmed on Friday, with the Bulgaria Under-21 international joining Wanderers team-mate Hayden White at Brunton Park.
"He's hard working, tenacious, good ability and brave with an eye for goal," Curle added.
"He knows when to gamble but we need to give him the ball."
