Kenny Jackett is confident that his side has what it takes to start climbing the League One table.
Tuesday night’s draw with Burton means six points have been accumulated from the opening six fixtures.
That means Pompey currently lie 18th in the table, albeit with as many as three games in hand over other sides in the division.
And Jackett believes that will improve, once his troops start to find more consistency in their displays.
The Blues boss said: “It’s six points from six games. We’re in 18th position and – despite going through in the cups – our priority is always the league.
“We’re looking to go further than last season and although it’s still early days, of course we want to improve.
“We didn’t get the result we wanted on Tuesday night after making a really bad start. We looked nervous and timid.
"I do feel that if we get our game right, we can beat anyone in this division."
“I was pleased that we kept going and got a point out of the game. That’s something, but not exactly what we wanted.
“We were searching for a performance and a convincing victory – and we’re still looking for that. We’re capable of it.
“A win is needed to turn things around and give us a bit of momentum, but I do feel that if we get our game right, we can beat anyone in this division.
“There have been times during the campaign so far when we’ve looked a good team, but just haven’t been consistent enough.”
Pompey travel to Wycombe on Saturday to face a side who have lost just once the league so far this season.
Jackett said: “They’ve had a very good start and we understand it’s a tough place to visit. They look like they’ve recruited well.
“It’s been a positive opening for them I’m sure Gareth Ainsworth will be looking to continue that to take one of those three promotion places.”
