Gillingham boss Andy Hessenthaler says striker Stefan Payne needs to believe in himself more, if he is to become a first-team regular.
Payne has started just two games since his move from Fulham in 2010.
Hessenthaler told BBC Radio Kent: "I've chatted to him. He knows what I think and what he has to do. We believe in him, that's why we brought him in.
"He's got to bring some self-belief, not just on a Saturday, but I want to see it in training during the week."
The majority of the 20-year-old's appearances for Gillingham have come from the bench.
He came on as a substitute to score the winner in Gillingham's 3-2 victory over Bournemouth in their FA Cup second round replay.
