Cheltenham Town provide the opposition as John Mousinho aims to build on a solid start as boss.
After starting with a preferred 4-3-3 formation, the Blues head coach has switched to a 4-2-3-1 in the past two games.
How he goes about tackling the Robins, who play with a back three will be interesting, as will the players employed.
Here’s how we think Pompey will line up.
