The 27-year-old defender is surplus to requirements at Spurs this summer despite having a cameo against Brentford last weekend.
He is in the final year of his contract and Tottenham are keen to offload him in order to earn a fee from his departure.
However, the defender has already rejected an offer from Spartak Moscow despite Spurs accepting a bid from the Russian outfit.
And according to French sports daily L’Equipe, Monaco are now emerging as a potential destination for Sanchez.
The Ligue 1 giants have their eyes on the Spurs defender and are showing concrete interest in signing him.
They are yet to make an offer for the defender but are almost certain to put in a bid for him in the final weeks of the transfer window.
Monaco are prepared to make a real push to take Sanchez to the Principality in the ongoing transfer window.
