Sevilla have no plans of listening to offers for Jules Kounde amid reported interest from Chelsea and Manchester United.
Kounde was heavily linked with the Blues during the summer, but their only offer of around £42m was turned down.
They have been fancied to make a fresh move in January, but they could face stiff competition from the Red Devils.
According to Marca, Sevilla have no room for negotiations for the Frenchman when the transfer window reopens.
They are reluctant to lose their prized asset. Any interested club must trigger the £69m release clause to sign him this winter.
Kounde reportedly agreed personal terms with the Blues, but Sevilla were unwilling to negotiate with the west London club.
They were initially open to a dialogue, but changed their stance as they were unable to find a suitable replacement for the Frenchman.
Aside from Chelsea and United, Real Madrid have also been regularly linked with the centre-back, who was previously at Bordeaux.
