Although Everton is reluctant to let Branthwaite go, the club is open to selling him for a price of £70 million. In the previous summer transfer window, Everton held firm on their valuation, rejecting three offers from Manchester United for the defender.
Branthwaite is said to be eager to experience European football at the highest level, which could make him more willing to join Tottenham if they meet Everton's asking price in the coming days.
It remains to be seen whether Tottenham will be able to negotiate a deal with Everton and bring Branthwaite to the club.
