The journey will have provided John Mousinho with plenty of time to ponder this starting XI for the game.
And with the previously suspended Joe Rafferty and Joe Morrell both back for the fixture against the Tykes, and Christian Saydee closing in on a return after injury, there’s plenty to consider.
Whatever decision is taken will be made tougher by the fact the Blues came from a goal down at Derby on Saturday to rescue a point at Pride Park.
So what does Mousinho do for his unbeaten side’s latest challenge? Does he stick to the team that served him well at the Rams, or does he freshen it up, with the likes of Tino Anjorin also waiting on his first start.
Here’s how we think the Blues will line up tonight against Barnsley.
5. Central defence 2: Conor Shaughnessy
The impressive Irishman continues to impress and deservedly keeps his place in the team to face Barnsley - much to the frustration of Ryley Towler and Sean Raggett. Photo: Jason Brown
6. Left-back: Connor Ogilvie
The former Gills man had a Battle Royale at Derby but came through well - as expected. Has been an ever-present in a back line that has conceded just three goals this season. There's no need to change that. Photo: Jason Brown
7. Midfield 1: Marlon Pack
Pack has been building momentum in recent games - which has been what Pompey have needed as they negotiate their way through a tough run of games. His presence will be important tonight against the likes of Herbie Kane, Adam Phillips and Jon Russell. Photo: Jason Brown
8. Midfield 2: Joe Morrell
The Welshman will have been disappointed with himself following his two red cards against Posh. Like the Swanson situation, it will be disappointing for someone to be dropped following the team performance against Derby on Saturday. But Morrell's experience and tenaciousness will be key tonight. Discipline will be a necessity, too, though, so needs to avoid any stupid bookings. Photo: Jason Brown
