Oli Hawkins insists that Pompey are still confident of securing second spot in League One.
The Blues won 3-2 at Wycombe on Saturday – courtesy of Jamal Lowe’s strike and a Brett Pitman brace – to record a fourth successive third tier victory.
Barnsley currently occupy the final automatic promotion position and were beaten by Burton, meaning they are now only above Sunderland on goal difference.
Pompey are two points further back in fourth, but Hawkins believes that they can close the gap with six games remaining.
The striker said: “I think that if we can keep winning then there’s no reason why we can’t nick the second promotion spot.
“The boys are all confident and that form we showed in the first half of the season seems to be back again.
"We’re holding on to leads and all we can do is our best in every game."
“We had a great achievement the previous week in front of so many people at Wembley, but it’s back to reality now.
“Our league form is really good at the moment. We’re holding on to leads and all we can do is our best in every game.”
Pompey twice led by two goals at Adams Park, only for a Scott Kashket stunner to ensure a nervy finale.
Hawkins said: “It was a tough game and we knew what Wycombe were all about, with a lot of set-plays and balls into the box.
“We did well in the first half and had a few chances. We looked comfortable and could have scored more, but the referee was giving some strange free-kicks against us and it was difficult.
“But we coped with the pressure they put on us towards the end and I’m glad we were able to hold on for the three points.
“Instead of keep running back and forth, I stayed back for the final few minutes and just tried to win a few headers for the team.”
