Chelsea are eyeing Tottenham goalkeeper Hugo Lloris.
Blues No1 Thibaut Courtois is a major target for Real Madrid this summer and Chelsea have drawn up contingency plans should they lose the Belgian.
And Spain's ABC reports Lloris is their top target.
Tottenham will not welcome an approach - particularly from Chelsea. Lloris recently extended his deal with Spurs to 2022.
Chelsea's move could be a suggestion from former keeper coach Christophe Lollichon, who remains an adviser to owner Roman Abramovich.
