The QPR manager insists that, if teams come in for his biggest-earning players, they will have to buy them permanently and take their wages off his hands
Last season's relegation has prompted the club's biggest stars to look elsewhere, with the goalkeeper linked with Napoli and the Morocco international linked with Olympique de Marseille.
While Redknapp accepts that he would sell if they want to leave, he has no intention of sanctioning a temporary deal, preferring to get their large salaries off the wage bill for good.
He told Sky Sports News of Cesar: "I can't see the sense in loaning him for a year.
"He's got three years left on his contract, he's just played for Brazil in the Confederations Cup and been absolutely fantastic. I think he's a goalkeeper for any team in the world he's that good, so to loan him out for a year and then have him back is absolutely pointless.
"What's the point in loaning him for a year then getting him back on massive wages for another two years?
"If he wants to leave, we sell him. Napoli are not short of money so, if they want him, surely they've got to come and do a deal. We have to do a deal that suits the football club and not deals that suit agents and other people.
"There's talk about [Taarabt] going to Hull on loan. What's the good in that? If he wants to go, let somebody come and pay the money for him."
