The Blues have an injury doubt in Marlon Pack heading into the game, with the club captain nursing an ankle injury from Saturday’s win against Wigan.
Connor Ogilvie, Anthony Scully, Kusini Yengi and Tom Lowery also remain out, leaving John Mousinho with a bit of a selection headache.
But with the Blues in impressive form this season and having plenty of options within the squad to chose from, there’s no need to panic.
Here’s how we believe the Blues will line up tonight, despite the absence of some key players.

18. Sub 6: Gavin Whyte
Whyte has had a slow start to his Pompey career, hence why the winger has been on the bench lately. Run-out in the second half against Wigan, however, was encouraging to see. Photo: Jason Brown
19. Sub 7: Tino Ahjorin
The on-loan Chelsea ace is slowly but surely building his fitness up but will have to do via the bench again against the Chairboys. Photo: Jason Brown
