Barcelona announced on Monday that Brazil international Arthur will join Juventus at the end of the season on a five-year deal.
The deal has been rumored for some time now but has finally been completed. The 23-year-old will finish the season with Barca and then complete his move to the Serie A champions.
Juventus will pay €72 million, plus €10 million in variables for Arthur. The club are expected to announce Miralem Pjanic will move the other way shortly.
Arthur initially insisted he did not want to leave Barcelona when speculation first arose, but he has been convinced to leave the club after less than two seasons and move to Italy.
Barca and Juve were in a rush to get the deal done before the end of the month for accounting reasons.
Arthur could still feature for Barcelona tomorrow against Atletico. The midfielder was back in training on Monday, after flying out to Turin over the weekend for a medical, and is in the squad.
