The Blues boss ranks the current injury and unavailability the worst he’s know in his time at Fratton Park, with a huge swathe of key players sidelined.
Mousinho faces a test to put out a competitive side against Kieran McKenna’s men, with Conor Chaplin also unavailable as part of the terms of his Pompey loan.
Here’s how we think the Pompey boss will go, as he takes on the huge challenge of bouncing back from the New Year’s Day mauling at Bristol City.

Will have an eye on a start after Schmid's errors at Bristol City, but the Austrian has a lot of credit in the bank still. Photo: Graham Hunt
14. Sub 2: Ibane Bowat
The back three clearly didn't work at Bristol City, with Bowat the man likely to make way if it is a return to a back four against Ipswich Town. Photo: Simon Roe

16. Sub 4 Jacob Farrell
Welcome back to the Aussie, who can hopefully now prove his fitness with a run of availabilty. Photo: Simon Roe
