"I have a lot of respect for (United manager) Louis van Gaal, but Sergio will be staying with us," the Real Madrid manager said at a press conference in Australia prior to the team's friendly against Manchester City.
"He is our player, our captain. I would like to see him (at the club) at the beginning of the season, because he's a key player for us."
When asked whether he was absolutely certain the centre-half would stay, Benitez said: "For me, 100 per cent.
"I insist that it is clear for me and the club, Sergio will be here. Football is a curious world, but Ramos will be staying."
Ramos has won a host of honours - including the Champions League - since joining Real Madrid from Sevilla 10 years ago.
The 29-year-old center-back has been appointed club captain this summer following the exit of long-serving goalkeeper Iker Casillas, who has joined Porto on a two-year deal.
