Tom Naylor believes Pompey have the quality required to remain at the top of the League One table.
With just a single defeat from the opening 16 games, they currently hold a two-point lead over Peterborough in second.
Naylor knows that the Blues will have to start turning draws into wins at Fratton Park if they are to hold off the chasing pack.
But the next home fixture is not until the end of the month and the midfielder hopes their fine away form can continue in the meantime.
He said: “I came up from League One with Burton and know what it takes to get out of this division, although it’s hard.
“But it’s certainly a lot easier when you’ve got players with the kind of quality that we’ve got here at Pompey.
"There’s been a lot of travelling, but that hasn’t seemed to affect us and we’re looking for another positive result on Saturday."
“Our away record has been very good and now we’ve got to step up our home form and pick up more points.
“We’ve got a few games on the road now, though, and hopefully we can collect three points at Bradford before having a little break from the league.
“There’s been a lot of travelling, but that hasn’t seemed to affect us and we’re looking for another positive result on Saturday.”
Naylor will aim to return to the side after being banned for last week’s draw at Accrington, having already accumulated five bookings.
He said: “It’s always frustrating when you have to miss out on game and I want to play every single one.
“But you’ve got to put your foot in where I play in the centre of midfield and make sure you do a lot of grafting.
“I’ve picked up more bookings then I did when I was playing at centre-half – it just seems to be something that goes with that position.”
