Juventus have reached an agreement to sign Barcelona midfielder Arthur at the end of the season.
The Catalonians say the fee will rise to €82m (£75m) after an initial payment of £66m.
The 23-year-old, who joined Barcelona from Gremio on a six-year contract in 2018, has made 72 appearances for the Spanish champions.
It is reported Juve’s 30-year-old Bosnia midfielder Miralem Pjanic will move in the opposite direction.
Arthur will continue playing for Quique Setien into August, in the latter stages of the Champions League, before being unveiled by the Bianconeri ahead of the 2020-21 campaign.
