Pompey are one of just four sides in the top four tiers of English football yet to lose a league game on home soil this season.
European – and world – champions Liverpool, along with West Brom and Wycombe, are the other sides who are excelling on their own patch.
But Kenny Jackett wants to see his troops improve their patchy record on the road in order to close the gap on the rest of the promotion-chasing pack.
They have won just two away matches – at Doncaster and Rochdale – ahead of Sunday’s trip to struggling MK Dons.
The Blues boss said: “While I was pleased with the Wycombe result on Boxing Day, we immediately changed our focus – as we always do – to the next one.
“We have to concentrate on improving our away form to really complement what has been an excellent record at Fratton Park.
"There are some really strong sides in the division and everyone will be hoping to go on a run, including us."
“We’re one of a number of teams in with a chance and if we get it right in the second half of the season, we can be right up there.
“It’s an open division, but that doesn’t mean it’s going to be easy and we’re going to have to work extremely hard.
“We don’t know what it’s going to take to get one of those three promotion places and it’s always hard to predict a points tally.
“There are some really strong sides in the division and everyone will be hoping to go on a run, including us.”
MK Dons are currently sitting in the League One relegation zone, but Jackett is expecting a tough test.
He said: “If you look at their home form, then they’ve produced some good performances against really big teams.
“It’s going to be a difficult game for us ahead of then facing a Gillingham side who are also playing well on their own pitch.”
