Chelsea are in talks with Sevilla over a swap deal for Jules Kounde.
The Frenchman is willing to join Chelsea but Sevilla are holding out for the right price.
Goal says the Blues have offered to include Kurt Zouma in any potential deal.
22-year-old Kounde is also a target for Manchester United, but they could move on after signing Raphael Varane from Real Madrid.
Kounde starred in Andalusia last season, making 33 appearances across all competitions.
He was then part of France's squad at Euro 2020.
Thomas Tuchel could turn his attention to Bayern Munich defender Niklas Sule if a deal for Kounde falls through.
