Chelsea have begun talks with Paris Saint-Germain to sign Presnel Kimpembe, as Thomas Tuchel continues to reinforce his defence even further.
Tuchel is keen to bring in three new centre-backs to replace Antonio Rudiger and Andreas Christensen, who both departed on free transfers this summer.
A deal for Napoli defender, Kalidou Koulibaly, is now at an advanced stage, with Chelsea having agreed a transfer fee of around £33.8m.
But Koulibaly will not be the only central defender heading to Stamford Bridge this month.
Co-owner Todd Boehly has also now opened talks with PSG over Kimpembe.
Negotiations are not at an advanced stage yet, but the Ligue 1 champions are open to selling the 26-year-old if their valuation is met.
So far that has not happened, with The Independent claiming that PSG have set a price tag of €50million (£42m) plus €10m (£8.5m) in bonuses.
