Pompey have received plenty of deserved praise for their form at Fratton Park this season.
They have yet to taste defeat on their own patch in the league, while Premier League giants Arsenal had to work hard for their FA Cup victory on Monday night.
But Ross McCrorie knows that their record on the road also has to improve if the Blues are to secure automatic promotion.
And they have one of their biggest challenges yet on Saturday, with a trip to a Peterborough side who are the most prolific goalscorers in the division.
McCrorie said: “This is the business end of the season and there are a lot of games coming up now, but we’re looking forward to it.
“We’ve got plenty of confidence when we play at Fratton Park and the fans have been absolutely amazing.
"Peterborough need to win to stay in the race and we want to build a gap to the teams behind us."
“I don’t know why we haven’t been as strong away, but it’s something we do need to sort if we want to win promotion.
“It’s a huge game for both sides this weekend – Peterborough need to win to stay in the race and we want to build a gap to the teams behind us.
“They’ve got a fantastic forward line who have scored plenty of goals and so it’s going to be a real test for us.”
Rangers loanee McCrorie has seen plenty of action in recent weeks following his recovery from a hamstring injury.
He said: “The gaffer’s been careful with me since I’ve been back and it was important to build my strength again.
“But he’s shown his trust in me by playing me quite a bit lately, which is something I’m really happy about.
“I’m feeling fit and strong now, while I perhaps came back a bit too quickly from the last injury. I got a bit more time on the training pitch for this one.
“I’ve been hampered by a couple of problems, but I’ve still played a lot of games and want to keep helping the team.”
