It's the day many Exeter City fans have been awaiting for, as the Grecians take on one of Brazil's top clubs to mark the centenary of their historic match against the national team.
They're in Rio to take on Fluminense in the same stadium where they played Brazil 100 years ago - and will even be using the same ball.
The anniversary has caused a lot of interest in Brazil and led to Exeter City becoming well known among football fans there.
At St James Park there's a day of Brazilian-themed entertainment to celebrate the match - and Radio Exe's Matt Young will be there from 4pm.
