The KNVB is a household name in the Netherlands. With 1.2 million members, the KNVB is the biggest sports association in the country. The majority of its 70,000 youth football trainers are volunteers. We teamed up to give them the right training tool, Rinus. Inspired by the legendary Rinus Michels (1928 - 2005), who was named by France Football and by FIFA as the leading coach of the 20th century.
