The Super Eagles ace scored three goals in three games for the Hornets last month, including a match-winning double during the excellent 2-1 away win over Newcastle United.
Ighalo’s other goal was his memorable strike against Swansea City at Vicarage Road, which helped to secure the Golden Boys' first three points of the season.
Also on the shortlist are Jamie Vardy of Leicester City, Dimitri Payet of West Ham United, Tottenham Hotspur’s Hugo Lloris and Manchester United duo Anthony Martial and Daley Blind.
The winner will be announced on Friday at 6am.
