Fernando Llorente is understood to have rejected a new contract with Athletic Bilbao.
The striker has been linked with a number of clubs around Europe following his 24 goals in all competitions for the Spaniards last season.
The 27-year-old, who will be a free agent next summer, is now believed to have turned down a deal worth around £3.5m per year, according to ETB.
Juventus, Barcelona and Real Madrid are all thought to be interested in Llorente.
