Guy Whittingham explained age will be no barrier as he attempts to get Pompey through the season.
The caretaker boss is keen to build a squad with one eye on the future as the Blues search for some semblance of long-term stability.
But Whittingham insists he will look to players both young and old to put a group together with a good sense of balance.
Whittingham has already recruited the likes of Ricardo Rocha and David Connolly, who are both in the twilight of their careers.
And defender Sam Sodje is set to arrive at the club at the age of 33.
The side’s average age is brought down by youngsters being brought into the first-team picture such as Dan Butler and Jed Wallace.
And there are players like 21-year-old Sunderland midfielder Adam Reed all set to come in on loan this week.
Whittingham said: ‘We have to plan for next season.
‘We are looking at the younger players and seeing if they are ready for the ups and downs.
‘Then we need the senior pros who we want to be decent players but also decent people.
‘Then they can help the younger players come through.
‘The players we get now will either be younger players who are hungry or senior players with character.
‘I don’t look at age. I look at what is in front of my eyes.
‘You want good professionals. That’s what we are looking to bring in.’
Pompey were hit with a postponement for the second successive weekend when Saturday’s clash with Scunthorpe bit the dust because of a frozen pitch at Glanford Park.
That follows on from the Fratton Park meeting with Notts County being scrapped due to a waterlogged pitch.
With heavy snowfall in the area in recent days, Pompey have also not been able to train at their Eastleigh base.
They report back today as they look towards this weekend’s meeting with Hartlepool at Fratton Park.
Whittingham knows his players are desperate to play.
He said: ‘The whole point of preparing for a week is to have a game on a Saturday.
‘So it’s been frustrating.
‘We prepared to travel up to Scunthorpe but didn’t train.
‘All you can do is prepare for games the best you can.
‘Training has been affected and the players want competition. They want to play on Saturdays and they want to win.’
