Dozens of public sector workers took the latest visit by FIFA secretary-general Jerome Valcke to the central city of Cuiaba as an opportunity to protest and demand a wage hike on Tuesday.

The group, including teachers and postal workers and backed by students, invaded the pitch at the Arena Pantanal, one of the 12 venues that will host World Cup matches next year.

Brazilian broadcaster Globo showed the 50-strong group booing as Valcke continued his latest visit to the host nation ahead of a visit to organizers in Rio on Thursday.
