Real Madrid president Florentino Perez wants to sign Chelsea goalkeeper Thibaut Courtois this summer.
Florentino has been considering both Courtois and AS Roma's Alisson Becker as he seeks a new keeper signing.
However, Marca says he has now made a final decision and will focus on settling terms with Chelsea over a fee for Courtois.
Roma are demanding €70-80m to sell Alisson, while Florentino is confident he can agree a deal with Chelsea for Courtois in the region of €35m.
With the Belgian now inside the final year of his contract, the president knows Chelsea must sell now or face losing their keeper for nothing in 12 months' time.
