Chelsea are targeting Inter Milan defender Milan Skriniar this summer after cooling on the idea of signing Juventus' Matthijs de Ligt.
The Premier League outfit have already lost two centre backs this summer, with Antonio Rudiger and Andreas Christensen joining Real Madrid and Barcelona respectively on free transfers at the end of their contract.
And with Thomas Tuchel's side potentially losing back-three option Cesar Azpilicueta as well, they have turned to Skriniar in the last few hours as an option to strengthen their backline.
The Blues were keen on Dutch star de Ligt, 22, but have deemed his £102million release clause too expensive, so have opted to pursue the Slovakian star.
