Pompey were looking to close the gap on the League One play-off spots when they hosted Wycombe.
But, unfortunately, a goalless draw on the sunny coast means they remain eight points adrift of sixth position with the same number of games remaining.
Marcus Harness knows that more was needed in an attacking sense against a well organised Chairboys outfit.
And the forward – returning after a three-match ban – was frustrated that the Blues could not offer more in front of goal.
He said: “We’re disappointed because we wanted to return to winning ways and keep our play-off hopes alive.
“It means we’ve got a big mountain to climb, but there’s a break now to recharge and then we’ll be looking to finish the season strongly.
"I’ve been pulling my hair out watching the boys from afar over the past couple of weeks."
“Wycombe make life difficult for you and you know what to expect, although I felt we looked solid defensively.
“We just struggled to get anything going offensively and that’s probably happened too many times this season.
“It was nice to be back personally, though. I’ve been pulling my hair out watching the boys from afar over the past couple of weeks.”
Harness was amazed that Ryan Tafazolli escaped unpunished after the referee somehow failed to spot a clear manhandling of George Hirst in the second half.
He said: “It was a foul and a red card. Perhaps he would have got it if he’d gone down, but you shouldn’t have to do that.
“It's as clear as day to me and so we’re disappointed that the decision wasn’t given. There’s nothing we can do about it now, though.”
