Over 40s football indoor or outdoor leagues in Brussels

Hi, anyone know of non 11 a side (ie 5 or 7 aside etc) indoor or outdoor football leagues in Brussels? Ideally for veteran age group / over 40s. I am looking to see what is out there and maybe put a team together to join once amateur sports restart. Ideally a set up which also provides the pitches so we wouldn’t need to have a home base. Cheers.
