Redknapp appeared to aim a jibe at Villas-Boas earlier this season when he claimed that big dossiers - a staple of the Portuguese's management style - can "baffle" players.
Shortly after taking over at QPR in November, Redknapp then told a press conference before his team's game against Chelsea that only a "dope" could fail to succeed at the west London club with the riches and players on offer.
When asked what he thought of Redknapp's claims, Villas-Boas replied: "Only if you manage a club you are going to find out.
"You have to be able to access a club like that to experience it.
"It's a different type of club. You just have to experience it and to survive it."
