Sergio Reguilon has been linked with a move to Chelsea this summer.
The Blues are targeting a new left-back this summer, with Reguilon among a number of names tipped to move to Stamford Bridge.
The Real Madrid full-back has spent the season on loan with Sevilla in La Liga, and lifted the Europa League trophy on Friday night following a 3-2 win over Inter Milan.
Reguilon has shone during his loan spell with Sevilla, making 38 appearances and scoring three goals.
He has attracted interest from Paris Saint-Germain, as well as the Blues, and Real Madrid boss Zinedine Zidane is reportedly happy to let him leave the Bernabeu this summer for a fee in the region of £22.4million.
That would be huge saving for Chelsea, who have also targeted Ben Chilwell from Leicester City, whom the Foxes originally wanted £80million for, but are set to accept an offer in the region of £50million for.
Chelsea have edged closer to securing a move for Chilwell, but Reguilon would still be available to them if the deal for the England man fell through.
Winning the Europa League was a great way for Reguilon to sign off from his loan spell with Sevilla, and he sent a message to the club's fans following the trophy triumph.
He posted a selection of images celebrating with the trophy on his official Twitter page and he said: "These photos cannot be defined in words... Thank you all from my heart."
