AZ Alkmaar vs Heerenveen prediction (Over/Under)

AZ Alkmaar were impressive in offense lasr season with 70 goals scored in 34 matches played. They played well in the preseason and had some impressive matches, scored 8 goals against Volendam, 5 against Fleetwood Town, 3 against Hertha Berlin. Alkmaar have signed some new players and their offense should be solid this season. Wout Weghorst has joined from Heracles (14 goals last season), Fred Friday came from Lillestrom and both strikers already scored few goals in the preparation matches. Heerenveen also had good results last season averaging close to 1.5 goals per game. During the preparation stage they had some very good games, scored 5 goals in each of the matches against Emmen and Oss. AZ Alkmaar and Heerenveen have combined four and six goals in their head-to-head matches in the previous season and I wait for goals in the opening game this season also.
