Barcelona defeated a number of opponents to land the signing of Brazilian superstar Vitor Roque,

According to GOAL, the 18-year-old forward will cost the Catalan giants and Athletico Paranaense €35 million (£30 million/$38.4 million) plus add-ons.

Vitor Roque's move to Barcelona was formally announced on Wednesday. The transfer fee might go to as much as €71 million (£60 million/$77 million).

Whether the Brazilian moves in the January transfer window or the summer after that is still up in the air.

The deal Vitor will sign has a release clause of €500 million (£427 million/$551 million) and extends until 2030.

The transfer fee will be paid in instalments and will be the biggest in the history of Brazilian football.

The bonuses are related to the number of matches played, goals scored and individual and team awards.

The deal, which has been weeks in the making, comes as something of a coup for Barcelona.

Sporting director Deco is credited with helping see off competition from the likes of Chelsea, Man Utd, Bayern Munich and Paris Saint-Germain to secure the player.

The deal will come as a relief to Barca fans after losing out to bitter rivals Real Madrid for the signature of another 18-year-old in Arda Guler.

Barca begin pre-season preparations in July as they head on tour to the United States.
