Pompey’s clash with Bolton at Fratton Park on Saturday is the first of four – possibly five – successive games on home soil.
Cheltenham also visit in the league on Tuesday night before contests against Harrow and Crystal Palace U21s in the FA Cup and Papa John’s Trophy respectively.
Then, after a trip to Wycombe that could be postponed due to international call-ups, there is third tier visit from AFC Wimbledon.
And it is a run of fixtures that Danny Cowley believes his side can use a springboard to relaunch their season.
The Blues boss said: “It’s good that we’re back at Fratton Park and have the chance to put right some wrongs.
“We can’t do anything about what’s already happened, but we can certainly affect what happens from now.
“We know it won’t be easy and we’ll need everyone. The Pompey supporters are intelligent enough to know they’ve got an important role.
“There are a run of four – potentially five – back-to-back home games, so this could be a turning point in our season.
“It’s been beneficial for us to have the full week in training, getting out on the grass and doing some good work with the team.
“We’ve conceded far too many goals of late, so to be able to affect our defensive principles is extremely useful.
"We can’t do anything about what’s already happened, but we can certainly affect what happens from now."
“We also need to be more ruthless because we didn’t get the value for our attacking display at Accrington last week.
“There was an improvement in the mental aspect of our game in that performance – we showed grit and determination.
“We now have something that we can really build on and so it’s vital that we do exactly that this weekend.”
Pompey’s opponents are three places higher in 13th spot, having climbed out of League Two last term.
Cowley said: “Bolton are very well coached and will still have some momentum from what they achieved back in May.
“Ian Evatt is making football management look pretty easy, with two promotions in two campaigns for him.
“We have plenty of respect for them and it’s a tough challenge, but also a great opportunity for us to bring some energy and intensity to our performance.”
Cowley had some good news about a trio of Pompey players who have been kept on the sidelines of late.
He said: “Paul Downing is back on the grass, which is a positive for us, and we’re hoping to have him available soon, while Ellis Harrison is probably another week behind.
“Liam Vincent is also making some good progress. It’s been great to see him with the ball at his feet over the past few days.”
