Mina only arrived at Camp Nou in January but despite showcasing his ability for Colombia at the World Cup, it has been suggested that the player could leave the Catalan giants due to the number of non-European players in their squad.
Jair is quoted by Mundo Deportivo as saying: "It is not true that Yerry has signed for Everton.
"Yerry has many teams who hold an interest in him but before we can think about that, we need to know what Barcelona plan to do. When we hear from the club, we will make a decision."
Mina made six appearances for Barca during the second half of last season.
