The 20-year-old has been linked with the likes of Arsenal, Tottenham, Juventus, Liverpool and Inter Milan in recent weeks.
Vekic told Sport: “Bojan will not leave. The club would not accept it. Next summer we will analyse the situation again and we will see, but for now he is happy at Barcelona.
“He is not getting many minutes but every time he gets an opportunity he has played very well. He managed to get a goal against Real Sociedad at the weekend.”
