Barcelona have agreed to sign France centre-back Jules Kounde from Sevilla for a reported transfer fee of 50m euros (£41.85m).
The deal is subject to the completion of a medical.
Kounde, who has won 11 France caps since his debut, had been linked with a move.
In his first season at Sevilla, the defender won the Europa League after joining from Bordeaux.
He started in the Nations League final for France.
Kounde's imminent arrival at the Nou Camp follows Barcelona's signings of Poland's Robert Lewandowski and Brazil's Raphinha for a combined total of over £50m.
Ousmane Dembele has signed a contract extension and two other players have joined the team on free transfers.
