Portsmouth striker Matt Tubbs says Andy Awford's side still believe they can reach at least the League Two play-offs this season.
Pompey are currently 12 points short of the top seven, and seven points above the relegation places.
But Tubbs, 30, insisted the side are still aiming high with 16 games left.
"I think we've got to be ambitious," Tubbs told BBC Radio Solent. "If you're looking over your shoulder then it's a negative thought straight away."
Tubbs arrived at Fratton Park on a two-and-a-half-year deal in January after being released by Bournemouth.
The forward has one goal in seven appearances so far and knows it is vital for him to get on the scoresheet on a more regular basis if they are to continue climbing the table.
"There's no reason why we can't look upwards," he added. "We have to be positive, and we'll look to pick up points when and where we can.
"The last four games we've had four clean sheets, and that's fantastic for any team in any division. The front players and midfield players will always create chances at the other end, and it's down to the strikers - me included - to put them away."
