The nominees for League One's January Manager of the Month have been revealed as Joe Dunne, Russell Slade, Dean Smith and Mark Warburton.
Colchester United boss Dunne saw his side collect seven of a possible nine points in a depleted month.
They convincingly saw off Gillingham and Carlisle United by 3-0 and 4-2 respectively to inch closer to the top half of the table.
Slade's Leyton Orient remain in the hunt for automatic promotion after a perfect four-from-four January, conceding just one goal in the process.
Walsall, under the guidance of Smith, had a busy six-game fixture list and went unbeaten with three wins and three draws to move into the playoff places.
Finally, December's winner Warburton and his Brentford side continued their scintillating form.
The Bees haven't lost since mid-October and last month scored 10 points out of a possible 12 to retain top spot.
The winner will be announced on Friday.
