Under-23s coach Radhi Jaïdi expects to meet a strong Leicester City side when the Midlands outfit travels to Staplewood Campus this evening.
Saints will take confidence from their recent form, and the home advantage, but their Leicester counterparts are enjoying a successful PL2 campaign, and have talent aplenty across an experienced squad.
The tie will be a one off 90 minutes, where the victors progress to the last eight of this year's Premier League Cup. And Saints do have history with this competition, as Jaïdi hopes his latest Under-23s cohort can repeat the feat of their predecessors, who won the cup back in 2015.
"They're top of the table in Division One," Jaïdi commented. "They have some experienced and older boys. I reckon Leicester will be a strong team.
"Definitely it's challenging and exciting. We've been on a good run, the confidence is high and hopefully it'll be another good test.
"We have our reference at home, we will be comfortable playing on our own pitches. It is going to be a technical game, and hopefully we'll have our own way to impose our style of play to get the win.
"Wins keep us going, it was nice to have another three points in our pocket [on Monday against Norwich]. Hopefully we carry on that feeling."
