The Blues did not make one signing, having missed out on number-one target Ben Woodburn.
However, a number of Pompey’s League One rivals did add to their ranks late in the window.
Here’s a look at how they recruited...
5. Paul Smyth (QPR-Charlton)

7. Matt Smith (Man City - Doncaster)

8. Charlie Mulgrew (Blackburn Rovers- Fleetwood)
