The Spanish coach has praised the appointment of the former AC Milan boss and expects him to bring back the virtues of the club
Benitez and Mourinho have had a tense relationship for a while as the Chelsea manager publicly mocked his successor at Inter last year, while also claiming the Spaniard wanted to remove photos of him during his time at the Nerazzurri out of envy.
The 53-year-old has now hit back at Mourinho, though, by implicitly criticising his rival's behaviour at Madrid in the past three years.
"Ancelotti is a great coach and a great person. He will somehow manage to restore the values that have always been important at Madrid," Benitez told AS.
"I have a good relationship with Carlo following our time in England and the Champions League finals between Liverpool and Milan.
"He is always polite towards other people. He's an educated guy, a good professional and always does his job well. He's won a lot of titles."
Ancelotti will be presented to the press as new Madrid coach on Wednesday at 13:00CET.
