Pompey fans are still coming down from the high of watching their club win at Wembley.
But Kenny Jackett does not expect to see any complacency creeping in as his side return to League One action.
The Checkatrade Trophy champions visit Adams Park this weekend to face a relegation-threatened Wycombe outfit.
And Jackett knows that victories are vital if Pompey are to keep applying pressure on the teams above them in the table.
The Blues boss said: “It was a unique occasion for us at Wembley and to come out on top made it a day that we could all enjoy.
“We have to take momentum from wins – and Sunday was a big one for us – because our aim is still to get promoted.
"We need to make sure our form is right and be there if the other sides slip up."
“Now we need to take that into the Wycombe game, but there is a big difference between confidence and complacency.
“The attitude has to be right and it’s important to realise that you need to earn whatever you can get – every point you collect is going to be hard fought.
“It’s a massive game for them and I’m sure they’re relishing the opportunity as much as we are, but we want to build on four successive victories.
“Second spot is still open and we have to keep pushing. We need to make sure our form is right and be there if the other sides slip up.
“If we’re not able to do that then we want to go into the play-offs full of confidence and playing well.”
The Chairboys have not won any of their past 10 games, but Jackett feels that manager Gareth Ainsworth deserves credit for getting them into the third tier.
He said: “For them to compete and survive in League One is, in my opinion, a great success.
“The fact that half the division is still looking over their shoulder shows you how tight it is and there are some big clubs below Wycombe.
“They should be proud of what has been achieved over the past seasons and we won’t be underestimating the opposition.”
Despite playing for more than 120 minutes, none of Pompey’s Wembley heroes are unavailable this weekend.
Jackett said: “All of the boys from Sunday are okay. Ben Close just came off with some cramp and I thought he played well.
“Bryn Morris will be added to the group, but Andy Cannon, Dion Donohue and Viv Solomon-Otabor – who are all coming along well – won’t be fit.”
