You have to travel back 16 years to find the last time that Pompey managed to win seven matches in succession.
That run – which stopped at eight victories – came at the start of the 2002/03 campaign and helped lay the foundations for securing promotion to the Premier League.
The latest sequence includes league successes over Bradford, Scunthorpe and Walsall, FA Cup triumphs at Maidenhead and Rochdale, and Checkatrade Trophy wins against both Tottenham and Arsenal’s youngsters.
It is points rather than cup progress that most concerns Kenny Jackett, though, and he hopes his side can continue their fine form.
The Blues boss said: “It’s a pleasing statistic to hear and we are ticking along nicely in all three competitions.
“What was effectively our second string on Tuesday night produced a good performance – both as a team and individually.
"We have to break each match down individually and take confidence from the last one, while also focusing on what’s ahead."
“Now we quickly swing back to what is undoubtedly our priority, which is the league, and look forward to a vital run of games.
“We have to break each match down individually and take confidence from the last one, while also focusing on what’s ahead.
“If you go with a humble mentality of making sure you work hard enough to earn your points, then hopefully it will help you keep a degree of consistency.”
Pompey will have to see off Chris Powell’s mid-table Southend side if they are to extend their sequence.
Jackett said: “They have not scored too many goals and not conceded too many either, so they’ve been quite consistent in that sense.
“I think they’re more than good enough to compete in this division and have a strong squad – now their challenge is to transform into a top six side.
“It’s a different type of challenge for us, but it’s the most important game of the season because it’s our next one.”
Jackett will have Tom Naylor available against the Shrimpers after the midfielder recovered from a minor groin injury.
He said: “Tom has trained this week and is fit for Saturday, but David Wheeler is still out and while Dion Donohue is back in full training, he’s not quite ready to play yet.
“As we stand at the moment, it’s a relatively fit squad we’ve got and that can only be good news for me.”
