In an official statement on the CMVM, Benfica announced that Spurs are paying a €3m loan fee for Vinicius.
The London club will have the chance to make Vinicius’ move permanent next summer for €45m – considerably less than his €100m release clause.
Jose Mourinho has been searching far and wide for a Harry Kane deputy, with a number of players linked.
He has found one in his homeland of Portugal by striking a deal for the highly-rated Vinicius.
Another English team, Wolves, had a €60m bid for Vinicius rejected earlier in the year.
The always reliable Romeo Agresti of Goal Italia reveals that an attempt was made to sign the 22-year-old.
However, Juventus consider him unsellable and part of their future project.
Demiral joined Juve from Sassuolo last year for a fee of €18m, becoming the first Turkish player at the club.
In January 2020, he suffered an anterior cruciate ligament injury, sidelining him for months.
On July 1, Demiral finally returned to action for Juventus, coming off the bench against Roma.
