In recent seasons United have had a strong second half to the campaign to clinch a European place and a similar run is required once more.
United are eighth in a congested table ahead of the Tayside derby after losing 2-1 at Hearts on Sunday, contributing to their own downfall with poor defending gifting the opener before they conceded a penalty to fall two down, leaving too much work to do to respond.
"I'm always confident we can go into games and score goals," Daly said.
"It's just trying to stamp out the silly goals that we're conceding. It's something that we need to address and we need to address it quickly because the games are coming thick and fast now.
"We don't want to find ourselves falling behind. We want to get right back into the group and that starts on Wednesday against St Johnstone."
The Irishman, who has scored 10 goals this season, does not expect to be asked to fill in at centre-back, as he has done already this season.
But he knows any errors will be exploited by Saints at Tannadice on Wednesday.
"If we're playing the way we're playing at the moment and giving silly goals away, they'll punish us," Daly said. "We've got to work on that and make sure we don't give away silly goals.
"The last home game against Inverness we had to score four goals to get a point. When you're scoring four goals in a home game you should be winning them."
