Neymar has blasted the conditions that Brazil faced during their 2018 World Cup qualifier against Bolivia on Thursday night.
Brazil, who have already booked their spot at next summer's tournament, played out a goalless draw with Bolivia at the Estadio Hernando Siles in La Paz.
The Brazilian players needed oxygen masks at full time of the match, which took place almost 12,000 feet above sea level.
Neymar, who played the full 90 minutes of the South American clash, posted on Instagram: "Inhuman to play in such conditions, field, altitude, ball... everything bad. But we were happy for the performance of the team even with these conditions."
Brazil will look to round off their qualification campaign in style when they host Chile next week.
