A youthful edge to the side certainly did not do Pompey any damage at Cardiff earlier this month.
They caused a Carabao Cup shock to beat their Championship opponents and progress to the second round.
So Danny Cowley does not believe age should be a barrier for another trip to south Wales to face Newport.
And he expects Pompey to remain competitive against opponents who have taken some notable cup scalps in recent years.
The Blues boss said: “We’re going to attack the game in the same way we did when we faced Cardiff in the last round.
“We also really want to put energy and focus onto the young players that we have at this football club.
"We saw the importance of the squad on Saturday, with players coming off the bench and making a huge difference."
“For them to be able to develop in the manner in which we want them to, we know they need some game time.
“So this match is a fantastic opportunity for that, as is the one at Crawley in the Papa John’s Trophy next week.
“We saw the importance of the squad on Saturday, with players coming off the bench and making a huge difference.
“They’re only able to do that if they’re match fit and ready, so a lot of our young ones will be involved at Newport.
“But we’re going there to try to win and have had a good luck at our opponents – between me, Nicky and the staff, we’ve watched all their games this season.
“They’re an organised team and are well coached, with lots of fluidity in and out of possession and difficult to break down.
“Newport have a brilliant cup record in recent times and so it’s a tough test that we’re really looking forward to.”
