Chelsea are unhappy with the asking price Sevilla are demanding for Jules Kounde.
Mundo Deportivo says Chelsea have been told they will have to shell out €70m to land Kounde this summer.
The race for the France centre-back is hotter than ever, though Manchester United's interest may have cooled following the arrival of Raphael Varane.
Sevilla are clearly in no mood to sell Kounde though, and have slapped a price tag of almost £70m on the 22-year-old's head. For his part, Kounde feels ready to move on this summer.
A swap deal involving Kurt Zouma could well help to drive down that cost, but the long-time Blues ace is thought to prefer a move to West Ham if he is to leave the Bridge.
