Arias, who impressed at the Club World Cup as Fluminense exited in the semi-finals to eventual winners Chelsea, bolsters Vitor Pereira's attacking options and comes in as a senior addition in the forward areas following Matheus Cunha's departure to Manchester United.
The winger will become Wolves' second signing of the summer after the £19.5million addition of Spaniard Fer Lopez from Celta Vigo.
