Chelsea are yet to make the breakthrough in negotiations to sign Sevilla defender Jules Kounde.
However, a deal remains far from straightforward with Sevilla reluctant to lower their valuation for the Frenchman.
Earlier this week, it was claimed that the Blues could sign the centre-back for an initial fee in the region of €50 million.
This has been dismissed by Fabrizio Romano, who claims that the La Liga outfit want the €80m release clause activated.
Sevilla also need time to find a suitable replacement, and they are unlikely to accept a deadline-day bid from the Blues.
The Blues are currently second in the Premier League standings after three games played. They drew 1-1 at Liverpool earlier today.
