Chelsea have advanced negotiations with Sevilla for defender Jules Kounde as they look to head off competition from Barcelona.
The 23-year-old is back on Chelsea's agenda along with Paris St Germain's Presnel Kimpembe after Manchester City blocked a move for Nathan Ake.
The Blues have held a long-term interest in Kounde as they were keen on signing him last summer, but were unable to get a deal across the line.
Thomas Tuchel is still trying to strengthen his defence after bringing in Kalidou Koulibaly from Napoli, having lost Antonio Rudiger and Andreas Christensen earlier this summer, and has turned his attention to Kounde once more.
