This season Mauves Army celebrates its 20th anniversary. Sunday's Brussels derby celebrates the group's anniversary year with a special shirt.

Bloq Nord - the lung of our stadium in stand 4 - is the home base of Mauves Army. The largest atmosphere group in the country has been driven by a passion for mauve and white for 20 years. It's where a young, mainly Brussels based audience expresses its love for Royal Sporting Club Anderlecht and thus contributes to the ever-increasing atmosphere that has characterized our stadium in recent years.

The shirt - with a subtle cameo print - bears the iconic print of the 2003/2004 season on the back. A reference to the year the group was founded. Fans can get their shirt in the fanshop on match day.
