Jules Kounde was not included in Sevilla’s squad for their final pre-season outing, raising the prospect of the player joining Chelsea.
Chelsea have had their eye on the French defender and have reportedly made a £55m bid to land their target.
Following the departures of Antonio Rudiger and Andreas Christensen and the aging Thiago Silva, Chelsea are looking for reinforcements and only recently brought in Kalidou Koulibaly from Napoli.
Sevilla’s 31-man squad for their upcoming trip to Portugal for their second training camp of the summer did not include the 23-year-old. The Frenchman was previously named in the La Liga squad for the trip to South Korea.
Kounde was expected to be Chelsea’s first signing of the summer, but with the takeover of the club and the departure of Marin Granovskaia as director at the club, progress appeared to have slowed.
Julen Lopetegui’s side will travel to Lagos on Thursday afternoon, ahead of this weekend’s friendly against Sporting CP.
