Pompey are making their own luck with injuries.
Kenny Jackett believes it’s no coincidence the Blues are doing a good job of keeping their players out of the treatment room.
Dion Donohue is set to make his return from a hamstring injury for the reserves against Bournemouth in the Central League Cup.
That leaves David Wheeler (back/hamstring) as the only senior figure not currently in contention.
A relatively clean bill of health has allowed for continuity in selection for Jackett during Pompey’s flying form this season.
That’s a far cry from last term when a crippling injury list hampered the Blues’ play-off bid.
Jackett feels a lack of injuries owes much to the medical team and the due diligence done when making signings.
But the Pompey boss feels ultimately it’s the approach of players to dealing with their rest and rehab from games which matters the most.
Jackett said: ‘We have done quite well, but I do think you do make your own luck in terms of injuries.
‘It’s players that you sign and your own environment and regime.
‘But most importantly it’s professionalism of the individual player.
‘That’s the most important thing.
‘You have to work hard - but also believe you make your own luck in that area.
‘We always look at ourselves first with injuries.
‘They are a big frustration and they can debilitate a football club.
‘You can pay people a certain amount out of your budget and then not call upon them at certain times.
‘It’s very frustrating.’
Tonight’s match with Charlton sees Pompey begin a gruelling run of eight games in 29 days which stretches through to the Checkatrade Trophy trip to Southend pencilled in for January 8.
Jackett knows such a run of fixtures will bring its own tests in terms of keeping players out of the treatment room.
The Pompey boss will have to manage his options for the Christmas period but is already prepared for what lies ahead.
He added: ‘You need your players focussed and you do need a degree of luck with injuries.
‘You need your squad ready because with the time between games you get very little time to react. It’s better as a club if you have contingencies in place.’
