Today marks the first day of the transfer window, with League One clubs having the rest of the month to complete deals they believe are necessary.
It represents an opportunity for all 24 sides to strengthen and bolster their ambitions for the remainder of the season.

17. Peterborough United
Darren Ferguson recently admitted that 'there will be potentially one in and one or two out' at London Road. Siriki Dembele has attracted interest from Newcastle, Celtic and Rangers but the Posh insist they're under no pressure to sell. Photo: Simon Davies
18. Plymouth Argyle
Ryan Lowe confessed funds are low at Home Park but the Pilgrims 'will try and do something but it has got to be for the right reason'. Lowe's also insisted Plymouth won't be selling Luke Jephcott, who's bagged 13 goals in just 19 games. Photo: Pete Norton
19. Pompey
A midfielder is Kenny Jackett's priority to serve as cover for Andy Cannon. However, Pompey could see Rasmus Nicolaisen and Cam Pring recalled by respective parent clubs FC Midtjylland and Bristol City. The Blues would then need to a new centre-back and left-back. Photo: Jason Brown
20. Rochdale
Not too much has come out of the Spotland camp, although it's likely there won't be too much in the budget to manoeuvre with. The Dale languish one spot above the relegation zone. Photo: Joe Pepler
