The shot-stopper had been heavily linked with a move away from the Santiago Bernabeu outfit this summer following reports that Los Blancos had met the €10 million release fee for Levante goalkeeper Keylor Navas.
Lopez’s agent, Manolo Garcia-Quilon, assured reporters recently that his client did not want to leave Spain this summer and that he had not received any enquiries for the 32-year-old from Napoli.
Benitez has now confirmed that the Serie A side are not interested in recruiting the Madrid goalkeeper.
"We have been linked with many names, but, a very high percentage are not real," Benitez told Marca.
"I heard: ‘Napoli will sign Diego Lopez, they have an agreement.’ In no time have we have raised [an enquiry]."
Benitez also spoke of Liverpool goalkeeper Pepe Reina, who spent last season on loan at the club.
Despite the player admitting that his future at Anfield was by no means assured, Benitez refused to reveal if he would attempt to sign his former player this summer.
“In principle, we do not speak of the transfer market because it would be disrespectful to our players," the former Reds boss mused.
“This time, lots of things have changed, but, today the goalkeepers that we have are of the highest of standards and we have the maximum confidence in them.”
