Agent Andre Cury has detailed how Barcelona are paying the fee of Vitor Roque.

The striker joined Barca in January from Athletico Paranaense.

"At the moment there's a queue of clubs that would be willing to sign him for €50m. Barca has only paid €10m so far, it's a detailed operation," said Cury.

“Barca pays €5m every six months until they reach €31m permanently.

“To meet all the variables, Vitor needs to be a starter. If he was a starter at Barca at 20, his valuation would be €200m.

“Barca will also pay €1m if he wins the Ballon d'Or and €2-3m for being in the three best in the FIFA vote.

“The rest comes from being a starter in half of the games ins his contract."
