Barcelona have confirmed that they have agreed a purchase option for Gremio midfielder Arthur, which will allow them to sign the player for an up-front fee of €30 million in the future.
The 21-year-old burst onto the scene in 2017 with a series of fine performances for the Brazilian club, helping them to the final of the Copa Libertadores.
Arthur then put in a superlative display in the second leg of the decider, as Gremio prevailed 3-1 on aggregate over Lanus to take home the famous South American trophy.
Links with Barca emerged almost as soon as the final whistle was blown, and he was even pictured in a Barca shirt alongside director Robert Fernandez in the aftermath of the final.
And while Philippe Coutinho's sensational arrival from Liverpool and Gremio's insistence on retaining their gem delayed negotiations, a deal has finally been struck.
"Barcelona and Gremio have come to an agreement to exercise a purchase option on Arthur Henrique Ramos de Oliveira Melo, which Barcelona will complete in July 2018," a statement posted on Barca's official website confirmed.
"Should the club finally take up the option signed, the transfer fee is fixed at €30m plus a further €9m in bonuses."
The midfielder has been called up to the Selecao but is yet to make his debut, although Tite is a confirmed fan of the young star whose confidence on the ball has led to early comparisons with none other than Andres Iniesta.
