Deep in the northern Brazilian state of Para is the village of the Kyikateje-Gaviao tribe, inhabited by some 300 indigenous people.
Its indigenous residents hold fast to many of their traditions, such as painting their bodies and playing indigenous games and sports.
As in the rest of Brazil, football is a popular pastime here, and five years ago the village team turned professional, calling itself the Gaviao Kyikateje Football Club. In 2013/14 it became the first Amazonian Indian club to compete in the first division of a state championship.
At first, the club was made up exclusively of indigenous players, but it has since become a mixed team, recruiting non-indigenous players to boost its ranks.
Today, there are four indigenous players in the squad. Striker Aru Sompre is one of them and the star of the team.
Indigenous and non-indigenous players all live together in the village in a three-bedroom house belonging to the club's president.
There is only one spot in the village where there is mobile phone reception, and players gather there at the end of their workout to speak to friends and family.
Traditional indigenous games such as log races are part of the team's training routine.
In the log race, runners take turns carrying a log weighing a minimum of 40kg (88lb) through the dense Amazon jungle.
Before a log race, the villagers and the runners all take a bath in the local river and sing traditional songs.
Players and villagers also pray together before every practice and every match.
While the facilities in the village are basic, the team has its own pitch where the players train twice daily.
Home matches are played in a stadium in the nearby city of Maraba, some 70km (45 miles) to the south-west of the village.
But this season has not been a good one for Gaviao Kyikateje. Even though they had already been relegated to the second division, they did not win a single match out of 13 played. Players are hoping their luck will improve in the next season.
