United are believed to have made a £28.6m bid for the Spanish international defender last month, with reports claiming that Ramos was keen on swapping the Santiago Bernabeu for Old Trafford.
So far this summer United have signed midfield duo Bastian Schweinsteiger and Morgan Schneiderlin, full-back Matteo Darmian and forward Memphis Depay, while Robin van Persie and Nani have both been offloaded.
Louis Van Gaal, however, is still keen on adding a world class centre-back to his squad but it would appear that will not be Spain star Ramos.
“In terms of Sergio Ramos, there’s a lot of talk about his situation,” Benitez told reporters in Melbourne.
“For me, he is an enormous professional. In person, he applies himself, he does everything that the team and I ask of him.
“And for me, the matter (is that) the president has already commented that he is staying with the club.
“I have spoken to him at length in the summer about his ideas, about his future. I see Sergio as an integral part of our team, he’s a winner and that’s what we need in our team.”
