Arias can play on the left and right, although he is not viewed as a direct replacement for Cunha.
Arias played at the Club World Cup this summer as Fluminense reached the semi-finals, where they were beaten by Chelsea, and will reunite with Wolves midfielder Andre, who he played with at Fluminense, and international team-mate Yerson Mosquera.
He has 31 caps for Colombia and won the Copa Libertadores with Fluminense in 2023 and leaves having played 229 times for the Brazilian side.
Arias becomes Vitor Pereira’s second signing of the summer after midfielder Fer Lopez joined from Celta Vigo.
