The Toffees see Aznou as a potential long-term replacement for Young, who played left-back for the team. However, they are not alone in their interest in the young player.
Other La Liga clubs, including Real Betis and Getafe, have also been linked to Aznou. This means that Everton will face stiff competition to sign him.
The left-back position is a key area for the team to strengthen, as they only have Vitalii Mykolenko who can play there naturally.
