Wagner Ribeiro is a FIFA agent among Neymar's 'people'. He was one of the people that hhelped bring him to Barcelona and despite the problems with the courts he is suffering, was also useful in helping Real Madrid sign Vinicius Jr.
On social media he published an image of flights in an airport, along with the text "green light, let's get to work". He spoke with radio station Bandeirantes and told them he was heading to the French capital.
Ribeiro is not an active part of the Neymar deal and his trip may be more about getting himself in the picture than actually making a difference in the deal.
