The Dragons head into tomorrow's clash with Scotland having scored only once in their last five games – Gareth Bale's effort in the 6-1 drubbing in Serbia last month.
That loss, coming after a 2-0 home defeat to Belgium, means Chris Coleman's bottom-placed side have no points from two fixtures in Group A so far and are in urgent need of finding some goalscoring form ahead of the qualifying double-header against the Scots and Croatia, who they take on in Osijek next Tuesday.
The issue is certainly not lost on former Wales striker Hartson, who netted 14 times in 51 matches for his country, but the 37-year-old reckons defending might be a more pressing concern right now and is confident the team has goals in it.
"It is a concern that you don't get goals from your frontmen, but it's not only your strikers you need to look at," Hartson said.
"It is the whole team we look at, and when the team is on the front foot and playing well, the goals will come.
"I think it's more of a problem of conceding them at the moment rather than scoring them.
"It (goalscoring) is not a major worry to us at the minute. If we weren't really creating chances I'd be more worried.
"Hopefully tomorrow we can create plenty of chances, get the crowd behind us and we can score some goals."
