With just short of a fortnight left for clubs to get their business done, the January transfer window is expected to come alive.

Though Burnley and Sheffield United are threatening to run away from the rest in the automatic promotion spots, there's still everything to play for in the rest of the Championship.

Just six points separate third place Watford and 14th place Reading in one of the tightest second tier campaigns in recent memory, while there's just a five-point difference between bottom side Wigan Athletic and 19th place Rotherham United.

Every club is looking for every opportunity to gain an edge over their rivals, whether that be in a push for the play-offs, or one final bid to beat the drop to League One.

Huddersfield Town, 22nd in the division, have been the most active so far (alongside Watford) as the Terriers attempt to add a bit more bite to their squad, while fellow strugglers Blackpool — now manager-less after Michael Appleton's departure — and Wigan Athletic have also been keeping busy.
