It's the highlight of any footballer's career - performing for their country in front of a global television audience of billions at the World Cup finals.
And for many of the game's biggest stars, their appearance at the Cup is something they'll want a document of forever, which inevitably means an onslaught of selfies on social media.
Neymar, who many considered to be Brazil's best hope of winning the World Cup on home soil, is undoubtedly the king of footballers on Instagram, appearing to document every crucial moment in the tournament with a grinning photograph of himself in various states of undress.
With more than 6 million followers, Neymar has posted 2000 images on Instagram and has given fans around the world a unique insight into the personal life of one of the world's best footballers as he performs on the sport's highest stage.
After scoring two goals in Brazil's opening match against Croatia, Neymar shared a selfie of himself with model girlfriend Gabriella Lenzi.
