The man in the middle
The Brazil v Mexico game will be overseen by Cuneyt Cakir, 37, the second Turkish referee in the World Cup.
It comes 40 years after Dogan Babacan officiated at Germany 1974.
Despite criticism for being a little too card-happy, the International Federation of Football History and Statistics (IFFHS) named Cakir as the fifth best referee in the world.
Brazil in particular will be hoping he'll be a little more lenient, with Neymar already on a yellow card.
