Tottenham are reportedly preparing a €10 million (£8.59 million) offer for Duarte, according to IDEAL.
The release clause for the Portugal international centre defender is €30 million (£25.75 million).
So yet, it’s unclear if Granada will be ready to trade the 26-year-old for a third of his release clause.
According to IDEAL, Tottenham head coach Nuno is the driving force behind the North London club’s interest in Duarte.

Nuno wants to play a back-three system at Spurs, similar to the one he used at Wolverhampton Wanderers, and he wants options.
Duarte is an excellent center-back who has previously represented Portugal on two occasions.
Since joining Granada in 2019, the 26-year-old has established himself as a vital player and has performed well for the Spanish club.
Last season, the centre-back made 27 starts in La Liga and eight starts in the Europa League, and he will make 34 starts in 2019-20.
Tottenham has already acquired Cristian Romero this summer, and a player like Duarte will only improve the club’s defensive capabilities.
Duarte’s mindset is extremely intriguing since he aspires to be like his Portugal international teammate and Juventus striker Cristiano Ronaldo.
We all know how amazing Ronaldo is and how he can still score goals for pleasure at the age of 36.
Despite the fact that Duarte is a defender and is ten years younger than Ronaldo, the former Manchester United and Real Madrid great continues to inspire him.
“It’s very tough to stay at the top for so many years like Cristiano does.
“Cristiano has skill, but his attitude is what sets him apart. He’s still eager to learn. From the outside, that’s what I see.”
