Sir Alex Ferguson revealed on Thursday night that he had received a letter from the Premier League asking him not to speak about the vacant position with the England national team.
Redknapp himself appeared unaware about the letter on Friday morning, telling a press conference: "I haven't received a letter, no. I haven't looked. Maybe there is one. I don't know whether there is a letter that has gone around to clubs. I don't know."
Ferguson is one of a number of top-flight managers who have backed the Spurs boss to take over from Fabio Capello, but it appears the Premier League are not happy with others tipping Redknapp for the position given that he is currently tied to a contract with Spurs.
Following his team's defeat to Athletic Bilbao on Thursday night, the Manchester United boss said: "The Premier League has written to me asking me not to talk about the England manager's job. I don't know why."
Redknapp is the overwhelming favourite to replace Capello as England boss and admitted last month that he was "flattered" to be thought of as the number one choice for what he sees as the "ultimate" job for any English manager.
After transforming Spurs from relegation contenders to a side capable of a top-three finish within the space of three and a half years, club chairman Daniel Levy is keen to keep hold of his current manager.
It has been reported that Spurs are willing to offer Redknapp a bumper new pay deal and a big transfer kitty to keep him at White Hart Lane, but the 65-year-old says he has not spoken to Levy about an extension to his current deal, which runs out next summer.
"That's not the case," Redknapp said, when asked whether he had been offered a new deal. "I speak to Daniel every day and he wants me to stay at the club, which is fantastic, but at the moment he has not made me an offer of a contract, no, and I haven't pushed for one either.
"We have not discussed how much money that is there to spend either. That has never come up in conversation at all."
