After the controversial SPL defeat to Celtic on October 17, United suffered two losses to Motherwell in four days, including Tuesday's reverse which saw them dumped out of the Co-operative Insurance Cup. Manager Peter Houston hopes to arrest the losing streak by encouraging his side to shoot.
"We need to score more goals from all areas of the park," said Houston.
"We've been working on finishing this week and a bit more shooting, more crossing - hopefully it will pay off."
Strikers David Goodwillie and Jon Daly have contributed eight of United's 10 top-flight goals this season. Morgaro Gomis netted against Hearts in August, while an own goal was scored in the Aberdeen meeting the following month.
"We can't just rely on Goodwillie and Daly to score all our goals," added Houston.
"I'm looking for when we get set plays, centre backs to chip in, I'm looking for midfield players from the edge of the box to shoot more, I'm looking for midfield players to get into the box.
"If you look at it Morgaro came on in the last 10 minutes against Hearts and scored a cracker from 30 yards.
"Scottie Robertson, Davie Robertson, Prince (Buaben) and Morgaro are all capable of scoring from that distance, so I feel they should do more shooting."
