Pompey host Peterborough this evening (7pm kick-off) in the first of a cup double, as they take a temporary break from their promotion bid.
Championship side QPR visit the south coast in the FA Cup at the weekend, but first up is a clash to decide who will reach semi-finals of the Checkatrade Trophy.
After topping their group, the Blues have seen off Arsenal’s youngsters and Southend to reach this stage.
Their visitors, meanwhile, finished runners-up to Luton before enjoying victories over Exeter and Chelsea U21s.
This is the furthest that Pompey have reached in the competition, while Posh lifted the trophy at Wembley back in 2014.
Both clubs have freely admitted that their number one priority this season is securing success in League One.
But each suffered defeat at the weekend, with United on the wrong end of a 4-0 thrashing at in-form Luton.
It was a contest between two unbeaten sides when Pompey and Peteborough met at London Road in mid-September.
Goals from Oli Hawkins and Jamal Lowe ensured it was the visitors celebrating a 2-1 triumph, leapfrogging their opponents into first position in the process.
TEAM NEWS
Kenny Jackett is likely to ring the changes for tonight’s tie, with teenagers Matt Casey and Dan Smith among those who could feature.
Oli Hawkins (calf), Luke McGee (wrist) and Nathan Thompson (hamstring) are all injured, while Andy Cannon and Bryn Morris are both cup-tied.
Louis Reed and Ryan Tafazolli are both suspended for Peterborough, with loan duo Kyle Dempsey and Ben White unable to feature, having already appeared in the competition for their parent clubs.
