Ipswich boss Kieran McKenna, Watford's Javi Gracia, Sergej Jakirovic of Hull City and Swansea head coach Vitor Matos have been nominated for the Championship's manager of the month award for December.
McKenna has moved Ipswich into the top three and within two points of second-placed Middlesbrough after taking 14 points from their seven games last month, which included two wins over leaders Coventry.
Watford reappointed Gracia as head coach in October and an unbeaten run in December has pushed them into the play-off places, with the Hornets currently on a four-game winning run in the league.
