Surfaced very late in the window after the Luke Graham deal didn't get over the line. Pompey paid Norwegian side Haugesund £600,000 for the 22-year-old, who's made one start and two sub appearances. | Simon Roe/ProSportsImages
18. Gustavo Caballero
A curveball as a loan deal was agreed with Santos for the Parguayan winger. Pompey can make the deal permanent, with the 2x-year-old's form variable amid nine outings so far. | Stephen Flynn/ProSportsImages
