Forest Green Rovers boss Dave Hockaday is concerned by the poor goalscoring form of his side in recent weeks.
Saturday's 0-0 draw at Cambridge was the third consecutive game that the play-off hopefuls have failed to score.
"It's about putting the ball in the back of the net. That's what we've struggled with the last three games," he told BBC Radio Gloucestershire.
"Performance-wise we fully deserved, in my opinion, to beat all three, [but] we didn't."
He added: "We're going to play the same way and look to dominate the game, and put the ball in the back of the net."
The point earned at Cambridge leaves Hockaday's side four points behind Grimsby, who occupy the final Blue Square Bet Premier play-off berth and have three games in hand over Rovers.
And 55-year-old Hockaday, who was recently linked with the Swindon job after Paolo Di Canio's resignation, admits his side's lack of goals could damage their hopes of reaching the play-offs.
"The teams above us might not be playing as well as us, but they're putting the ball in the back of the net better than us," he commented.
"They're not playing particularly well because of the pressure on them, but they do nail the key moments of the games.
"We need to be relaxed and keep on believing that our game is why we've got to be one of the best teams in the league and that will hopefully get us promotion, this year, next year or whenever."
