Mina is being linked to a big money move with the Blues.
But Jair Mina, the 23-year-old agent and uncle, says a decision over the Colombian international ultimately rests with Barca.
“It is not true that Yerry has signed for Everton," he told Mundo Deportivo.
“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."
