Sevilla have signed Marcos Acuna from Sporting CP to all but end their interest in fellow left-back Sergio Reguilon.
Reguilon starred on loan with Sevilla last season and the Europa League winners had hoped to re-sign him from Real Madrid for the 2020-21 campaign.
The defender made 38 total appearances for the club during his loan spell, scoring three goals, with two of those coming in La Liga and one in the Europa League.
With his future at Real Madrid uncertain, Reguilon had been linked with either a permanent transfer abroad or a loan back to Sevilla, which would have allowed him another season to prove he is ready for a regular spot at the Bernabeu.
