Cheltenham are the visitors to Fratton Park on Saturday, giving head coach another guaranteed selection headache as he weighs up his options.
Given the squad’s strength and depth – irrespective of injuries picked up by Tom Lowery and Paddy Lane in recent weeks – the likes of Zak Swanson, Ryley Towler, Terry Devlin and Ben Stevenson have had to spend time in the stands.
Meanwhile, Sean Raggett has not been able to nail down a starting spot as competition for starting places intensifies following a recruitment drive that has seen 13 new arrivals delivered to date during the current transfer window.
So what does Mousinho do ahead of his next challenge?
Well, here’s what we think he will do as the Blues prepare to face the Robins.
