John Mousinho’s men have picked up 10 points from a possible 12 and go into the game two points off the play-offs.

Both teams have injuries going into the game, though Pompey are set to welcome Josh Murphy and Conor Shaughnessy back into the fray.
Here’s how Blues writer Jordan Cross thinks Mousinho will go.
