Fratton Park is one of the more imposing football stadiums in League One.
But a look at the table will tell you that Pompey should have no qualms about being on the road again this weekend.
They have dropped just two away points from six fixtures this season, compared to seven on their own patch.
And Kenny Jackett is confident his table-topping outfit can return to form at AFC Wimbledon following last week’s defeat to Gillingham
The Blues boss said: “There’s no difference for us – home or away – in terms of what we do during the week.
“But I think perhaps the mentality of our opposition can be different and of course that will affect things.
"We’ve shown discipline and character on the road and we always set up in an attempt to win the game, wherever we’re playing."
“We have had two very good performances at home against Oxford and Plymouth, and I always think that home form is easier to get right than away form.
“We’ve shown discipline and character on the road and we always set up in an attempt to win the game, wherever we’re playing.
“It was a frustrating afternoon for us against Gillingham last week because we were in control, but didn’t turn our possession into shots.
“But we were pleased with Tuesday night at Crawley night – winning is winning and you want to experience it as much as you can.
“There’s no doubt, though, that the league is our priority and it’s a big game for us on Saturday. I’m confident we’ll have the right attitude.”
Pompey face a Dons side currently sitting just outside the drop zone following successive defeats to Bradford and Plymouth.
Jackett said: “They’ll be very positive on Saturday and there might be a derby feeling, with our allocation sold out at a tight ground.
“Both clubs will be well backed and that will contribute to a great atmosphere – I’m sure it will be competitive.
“You have to work hard for every point you get in this division and I have no doubt that it will be exactly the same this weekend.”
Jackett will have to do without the injured loan duo of Andre Green and David Wheeler at Kingsmeadow.
He said: “They’re both currently unavailable and I don’t think either of them will be playing this month – if they get back just inside October they’ll have done well.
“Dave got a kick on his ankle last Saturday and it’s come up quite a lot, so it’s a matter of weeks rather than days.
“The only other player we’ve got missing is Ronan Curtis, of course, who’s currently away with the Irish squad.”
