Pompey have enjoyed cup progress on two fronts over the past week, with victories at Fleetwood and Walsall.
But Kenny Jackett is pleased to be getting back to the bread and butter of League One football on Saturday.
AFC Wimbledon visit the south coast for the first fixture at Fratton Park since table-topping Wycombe were beaten on Boxing Day.
And although Pompey currently sitting in 10th position, Jackett is encouraged by the fact that very few points separate his side from the promotion spots.
The Blues boss said: “We’re delighted to get through in the cup games, but now we’re back to league action and that’s our priority.
“So we have to show that on Saturday with a really good attitude and appetite, setting the bar really high and making sure we play to our best.
"It’s a very open division and we’re the ones that have to capitalise on that because all three places are available."
“There are a number of teams that promotion is a target for – and I’m pleased to say that we’re one of them.
“It’s a very open division and we’re the ones that have to capitalise on that because all three places are available.
“We want to be one of those sides that, come May, are promoted to the Championship and will need a run between now and the end of the season.”
Pompey are facing a Dons side who will be trying to pull clear from the danger zone in the coming weeks.
Jackett said: “They beat us with a last-minute goal in a game where we dominated. It was frustrating to come away with no points.
“Like everyone, they have threats and they also have a nice shape about them. It’s mainly about our own team, though, and reaching our potential.”
The draw for the quarter-finals of the Leasing.com Trophy was held on Thursday and it handed Pompey a Fratton tie against Scunthorpe.
Jackett said: “We’re pleased to be at home and as the competition gets closer to Wembley, the teams that are fielded get stronger.”
