A total 32 teams competed in the league,[1] one of them coming from the fully professional 2009–10 Eerste Divisie, and the remaining 31 from the amateur 2009–10 Hoofdklasse.
The league was originally expected to feature two relegations from Eerste Divisie; this was however made impossible by the exclusion of bankrupt-collapsed HFC Haarlem from professional football in January 2010.
The league was originally announced to receive national weekly media coverage on Dutch TV channel RTL 7, with a one-hour synthesis of the games on Saturdays and Sundays.

[5] For the inaugural season of the Topklasse, 32 teams were picked, 31 of which coming from the Hoofdklasse, and one - FC Oss - being relegated from 2009–10 Eerste Divisie.
