David Haye's manager Adam Booth has played down reports that the former WBA heavyweight champion is plotting a comeback.
The Londoner officially hung up his gloves last month on his 31st birthday following a disappointing points defeat in his final fight with Wladimir Klitschko in July.
However, the Daily Telegraph claim Haye has held talks about a showdown with the Ukrainian's brother Vitali and is already training for spring return against the WBC champion.
Booth, who has guided Haye's career since the amateur ranks, confirmed offers have been put on the table but ruled out any imminent return for the former cruiserweight king.
"Yes I've had phone calls and communication," he told Sky Sports News HD.
"But as far as I'm concerned at the moment, the fight isn't happening and David is retired. That's all I can say.
"It's not for me to say, it's for David to say - it makes no difference to me."
Haye has at least returned to the ring at his old gym in London, sparring a couple of rounds with British and Commonwealth Super-Middleweight champion George Groves.
Groves, who is back in action on December 9th, says he would not be surprised if his old mentor did come out of retirement to face Klitschko.
But Booth, who joked Haye "wheezed his way through" a couple of rounds last week, says the heavyweight soon realised "how far back it is from retirement".
