Nice have made a £10m offer for Blackburn Rovers Chile international striker Ben Brereton-Diaz, 23, but face competition from Everton.
Brereton Diaz scored 22 goals in the Championship last term, and could now be set for a move to the Premier League if Everton can fend off Nice in the race for his signature.
Frank Lampard is desperate to improve his attacking options after selling Richarlison to Tottenham, while Dominic Calvert-Lewin is currently sidelined with a knee injury.
Brereton Diaz is not the only option for the Toffees, as they are still in the frame for Brighton striker Neal Maupay who has been discussing a £15m move to Nottingham Forest.
