The Bergamo side will pay €16 million to Juventus to secure the player's rights, clearing him for a move to the Premier League
Atalanta have activated their option to buy Cristian Romero from Juventus to clear the defender to join Tottenham, while Merih Demiral has joined the Bergamo side on loan.
Atalanta signed the centre-back on loan last season from the Bianconeri, adding an option to sign him on a permanent basis to the deal.
The Argentine's impressive displays in Serie A caught the attention of Spurs, who are reported to have agreed to sign him in a deal worth around €50 million (£42m/$59m).
