Oosting was accurate in the 8th and 13th minute against his father Joseph’s team. Only Rick Kruys scored in an Eredivisie match against his father in the 21st century. He did that in 2004 on behalf of FC Utrecht against De Graafschap. Jizz Hornkamp, also a debutant, made it 3-0 just before half time. With this, Willem II scored as much in one game as in the first half of the season.
Michiel Kramer did something back in the 71st minute, but RKC was no longer dangerous.
