The agent of Koke says the midfielder is happy at Atletico Madrid.
The midfielder has been linked with the ticket of Barcelona presidential candidate Josep Maria Bartomeu.
Iñaki Espizua told Radio Marca: "Not surprised, flattered. It's great to hear these kinds of things, especially from a club like Barça, but right now the player's position is very clear.
"He feels he is a key part of Atlético de Madrid's plans for the future and I therefore have very little else to add."
