The Blues moved to bring in seven new faces, before the cut-off point for trading at 7pm on February 2.
In addition to those signings there was a host of other names to surface from across Europe as Pompey cast their net wide for their additions.
Some of those players certainly had credence when it came to talk of a move, with others, well, less so...
We’ve tracked down all of the players linked with Pompey in the winter window, explored where they are now and their looked at their fortunes over the past couple of months.
9. Luke Graham
Pompey pushed until the death to bring in the Dundee defender. The £1.5m starting bid would have been a record for the SPL side, but the price continued to sky-rocket as they made their intention to keep the player now clear. Pompey could return for Graham in the summer, but the likes of Rangers and Celtic are now on his trail. | SNS Group
10. Ousmane Sow
Pompey wanted the Senegal winger, but Brondby were always in the box seat as he sealed a move to the Danish side for £2.6m. Two appearances so far in the league's championship round. | BELGA MAG/AFP via Getty Images
11. Jacob Brown
Was set to join Barnsley on loan, when Pompey's interest surfaced late in the window. Made a loan move to Fratton from Luton, with the attacker grabbing a goal from four starts and five sub appearances. | Graham Hunt/ProSportsImages
12. Keshi Anderson
A name which surfaced in the middle of the window, with a deal quickly agreed after Anderson became a free agent following his Birmingham exit. Two sub appearances, but been sidelined with a hamstring issues since. | Graham Hunt/ProSportsImages
