Only moves featuring at least one Premiership or Championship club are listed.
The winter transfer window opened on 1 January 2008, although a few transfers took place prior to that date; the first non-free non-loan move went through on 12 December 2007.
Players without a club may join one, either during or in between transfer windows.
Clubs below Premiership level may also sign players on loan at any time.
If need be, clubs may sign a goalkeeper on an emergency loan, if all others are unavailable.
