Chelsea are very eager to secure the signature of Sevilla's Jules Kounde this summer.
The center-half was a key target for the club last summer, but a deal did not materialize.
The losses of Andreas Christensen and Antonio Rudiger in the off-season will mean an even greater urgency to sign a top defender.
According to Goal.com, Kounde is still the club's primary target, and negotiations will begin as soon as Chelsea is officially taken over.
Sevilla need money to balance their books, but will want at least £59 million for one of their most highly rated players.
Kounde had a verbal agreement with Chelsea last summer, and is enthusiastic about completing the move this time around.
