Kenny Jackett hopes Pompey can forget their Fratton woes when they travel to Oldham this weekend.
They have failed to win on home soil in 2018 to slip away from the League One play-off spaces and down to 12th spot.
There has been better fortune on the road, however, with two victories – at MK Dons and Fleetwood – from the past three outings.
And Jackett wants to see his side collect another three points against a team unbeaten in five, but still sitting precariously above the drop zone.
The Blues boss said: “There are a lot of sides fighting now to pull out of and away from the bottom four.
“Any game in this division is a difficult one and Oldham are quite strong with their full squad available.
"We’re determined to finish this season as strong as we possibly can to build confidence."
“They’ve lost players for whatever reason during the course of the season, but we saw at Fratton Park that they have a strong team.
“The most important thing is how we do and our form away from home has been quite good of late, with wins at MK Dons and Fleetwood.
“We’ll have to be at our very best and focus on the good parts of our performance against Gillingham last week, while eradicating the poor bits.
“I’ve spoken in recent weeks about the top six, but being realistic we need a high numbers of wins.
“We’re going into the last 10 games and if it’s not to be, then we’re determined to finish this season as strong as we possibly can to build confidence.”
Skipper Brett Pitman is ready to face the Latics following a three-match absence with a hamstring injury.
Jackett said: “Pitman will be fine this Saturday and available for selection. That’s good news because he’s our captain and top scorer.
“There’s nobody else who’s going to be coming back against Oldham, but possibly the following week.
“We’ve been denied players who have done well for us over the course of the season and that’s cost us, so we need to make sure they recover quickly.”
