That is the verdict of Kenny Jackett, who is adamant he cannot sense any tiredness in his undefeated Blues.
Pompey's boss has maintained a consistent selection policy during the run which has catapulted the teamÂ to League One's summit, particularly in the past month.
A gruelling midweek victory at Coventry arrived in the midst of a testing spell of five matches in 15 days for the promotion-hunting side.
Jackett, though, pinpoints February as theÂ time to be concerned about fatigue.
In the meantime, he believes his players can cope with the demands expected.
He said: '˜There are times when you can just see on someone that it might be time to step out.
'˜I would say that's more about individuals rather than wholesale changes. In the main, your squad at this stage of the season should be fresh and should be okay.
'˜There are always individual situations, such as people's health, pre-season, things like that. ButÂ at this stage they should be the minority '“ the majority of the group should be ready to playÂ twice a week.
'˜From February onwardsÂ that can vary, once you get into 30-40 games you do see a slightly different game at that stage of the season, right across the country. I think fatigue plays a part in thatÂ period.
'˜That shouldn't be the caseÂ two months into the season '“ they've just had seven weeks off!
'˜As you get to know your players better and their character you know whether they are on it or not.
'˜There may be one or two who need resting, or maybe not. I am not looking to make changes just because we need them through freshness.'
In recent weeks, Brett Pitman has dislodged Oli Hawkins, while fit-again Jack Whatmough reclaimed his spot off Christian Burgess.
Otherwise Jackett has kept faith in the team which continues to excel.
He added:Â '˜Another thing is if it's a third game in a week.
'˜Generally, the travelling can take its toll a little bit and it's not always a physical thing either, butÂ mentally. People lookÂ a little jaded and half-a-yard down, it's not a conscious thing.
'˜With three games in a week and the last is away from home, like Donaster earlier in the season, it is pretty tough then.
'˜But for us it's not applicable this week, we have a home game.'
