Carlisle United manager Greg Abbott believes on-loan Watford striker Joe Garner can be the ideal influence for academy product Mark Beck.
Beck, 18, has featured in the first-team on a regular basis this season but has scored only once in 12 games.
"I think Mark needs to take a good look at Joe and the way he puts himself about," Abbott told BBC Radio Cumbria.
"He should realise how much of an impact he could have if he had the same determination and nasty streak as Joe."
Garner, now in his third stint with Carlisle after
extending his stay at Brunton Park until 20 November
, has scored seven times for the Cumbrians this term, including five in the last five matches.
However, Carlisle have been heavily reliant on Garner's goals, with the 24-year-old so far contributing 29% of the team's 21 league goals this term.
Abbott's options have been limited with senior strikers Lee Miller and Danny Cadamarteri unavailable, and Beck has been pressed into action.
"I was disappointed with Mark and I have told him so because he is a player that has got quite a lot of tools to be a really, really good player at this level," Abbott added.
"We needed him today and he has come up a little bit short, but he is 18, so the disappointment is that we think he is better than he probably thinks he is himself.
"He can make a bigger impact than he is making, and really be a thorn in opposition sides."
