Harry Redknapp, left, says he is unaware of a letter that has supposedly been sent to all the Barclays Premier League managers telling them not to tip him for the England job.

Sir Alex Ferguson revealed he had received a letter from the Premier League asking him not to speak about the vacant position with the England national team.

The Scot is one of a number of top-flight managers who have backed the Tottenham Hotspur manager to take over from Fabio Capello, but it appears the London club are not happy with others tipping Redknapp for the position given that he is currently tied to a contract with them.

Redknapp himself appeared unaware of the letter, saying: "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."

However, 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 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 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, which is fantastic, but he has not made me an offer of a contract, no, and I haven't pushed for one, either.

"Also, we have not discussed how much money there could be to spend."
