He scored four goals in 27 matches in the 198384 season. He went on to score nine goals in 31 games in 198485 and eight goals in 33 appearances in 198586. He then was signed by Eredivisie rivals AZ Alkmaar, and played 27 games in 198687, before scoring six goals in 17 appearances in 198788.

He scored six goals in 29 appearances in 198889, before moving on to RKC Waalwijk. He claimed two goals in 23 appearances in 198990, and then scored five times in 29 games in 199091.
