Pride as well as points was on the line last Sunday but arguably more is at stake against the Baggies, who find themselves being dragged into the relegation mire.
Victory for Pompey will see them leapfrog Eric Ramsay’s side in the table, as they look to continue their upwardly mobile league form.
John Mousinho’s men, of course, have a injury crisis to contend with, with 10 men out going into the game and players likely to feature carrying problems.
There’s also the four new faces signed so far in the January window to throw in the mix - here’s how we think Mousinho will go on another big afternoon at PO4.

15. Sub 3: Zak Swanson
Heroic performance last Sunday and every chance Swanson does start, with it a judgement call over the fitness of other options. Definitely has a big role to play. | Getty Images

16. Sub 4: Aji Alese
Welcome to Pompey, Aji! Lots of promising noises made over new boy, but hasn't played a senior game for a year. That likely means a start and being taken off or, as we've gone for, minutes off the bench. | Portsmouth FC
