The Marveld Tournament is an international youth football tournament organised by football club Grol. Youth teams (age category Under 15) from well-known professional clubs from the Netherlands and Europe, but also from other continents, come to Groenlo every year to compete against each other. The first edition took place in 1990, at that time one day and with only De Graafschap as a professional football club. In the meantime, it has grown into a four-day football event in which the youth teams of top clubs such as Ajax, Feyenoord, PSV, AZ, FC Barcelona, Real Madrid, Manchester United, Bayern Munich, Anderlecht and Paris Saint-Germain are regular guests. Football teams from Brazil, Mexico, the United States, Japan, Korea, Ghana and South Africa also like to come to Groenlo. A youth selection of the organising association Grol participates every year and may then compete against the football stars of the future.
