Matthew Amoah scored the winner for NAC Breda as they beat defending Dutch league champions FC Twente 2-1 on Saturday.
Breda's victory left Twente with its first league defeat since April 2009.
Twente appeared set for its ninth win of the season after Bryan Ruiz opened the scoring in the first half.
But two second-half goals by Ali Boussaboun and Matthew Amoah helped Breda to victory at home.
