It is reported by Marca that the deal has been closed for a fee in the region of €10m upfront plus a further €2m in variables.
Acuna scored twice and provided four assists at Sporting last season and has won 27 caps for the Argentine national side.
He is a versatile player who can also play higher up the pitch and in midfield roles, but is primarily a left-back.
Acuna came to prominence at Racing Club in Argentina before moving to Sporting CP in 2017, where he won the Taça de Portugal once and the Taça de Liga twice.
