Canberra United coach Elisabeth Migchelsen says Matildas striker Michelle Heyman needs to be more decisive in front of goal, but it shouldn't be left up to her to carry the attack.
Heyman will be chasing her first goal in more than 180 minutes when United hosts W-League cellar dwellers Adelaide United at McKellar Park on Sunday.
Migchelsen is yet to decide whether 15-year-old Grace Maher will become United's youngest-ever player and has warned her side against taking Adelaide lightly.
After finding the net three times in as many rounds to open the competition, Heyman has not been sighted on the scoresheet in a 2-0 win against Brisbane Roar and last week's 3-0 loss to Perth Glory.
Heyman is United's leading goal scorer this season, with Ellie Brush, Caitlin Munoz, Stephanie Ochs, Lori Lindsey, Grace Field sharing the rest with one each.
Migchelsen said it was up to Ochs and fellow wide attacker Ashleigh Sykes to provide Heyman with more support in the final third.
"If you have the opportunity in front of the box you need to finish," Migchelsen said.
"Maybe they get tired or maybe they wait too long to make a decision.
"If you don't make a decision, it ends up as nothing."
A two-time W-League golden boot winner, Heyman is expected to play a leading role for the Matildas at next year's women's World Cup in Canada.
"She has enough confidence, but that's not the issue with Michelle," Migchelsen said.
"I think it's more she needs to be in time in the 18-yard box and if she has chances she really needs to finish.
"Sometimes she hesitates and the moment is gone."
Central defender Grace Field could come back into the starting side after missing last week's trip to Perth with illness.
There could also be a W-League debut for Maher, who returns after representing the Australian under-16 team at the Asian Football Confederation under-16 championships in Malaysia.
If selected, Maher would be the youngest player in United's history.
The impressive performances of 17-year-old midfielder Julia De Angelis in her first season have shown that age isn't a factor.
"You need to bring them along slowly, have some game time then build it up," Migchelsen said.
"For example, next week you play against Melbourne and you need experienced players.
"If they're good enough and they can handle the pace of the game and the tactics, then why not."
Despite losing all five games so far, Adelaide showed in a 1-0 loss to Canberra in round two that it cannot be underestimated.
"So far they haven't won a game, but for me that doesn't change anything," Migchelsen said.
"If you want to reach the first four, then you need to win every game irrespective of who the opponent is."
