And that meant the Fratton Park lights were out well before Monday’s 11pm deadline.
The same couldn’t be said for the Blues’ League One rivals, though, with the majority involved in deals in some way or another.

Here’s an run through of what Pompey’s counterparts got up to ahead of the January deadline.
