Haye must not retire - Hatton
Haye claims he will hang up his gloves unless he is successful in his quest for a rematch with WBO, WBA and IBF champion Wladimir Klitschko, who outpointed him on Saturday.
The omens do not look good for Haye, with Klitschko's manager ruling out a reprise of their bout, meaning he faces the prospect of retiring following a comprehensive loss - in much the same way as Hatton bowed out.
And Hatton, who brought his career to an end on Thursday, agrees with those who think Haye should fight a couple of ranked heavyweight contenders - Chris Arreola and Alexander Povetkin, perhaps - before going after Wladimir or Vitali Klitschko.
"The decision is his but I think retirement is a bit too early for him," Hatton said. "I think he should give it a couple more fights. He still has a lot to offer."
Hatton has also hinted that Haye may regret his failure to break through Stateside; of his 27 bouts, only two have been outside Europe: against Roger Bowden in Florida, and Vance Winn at the Playboy Mansion in Beverly Hills.
"It would be nice for David Haye to see the Hayemaker's name up in lights in Las Vegas like I had. He's not had the chance to do that yet," said Hatton. "It would be nice for him to go to America, re-establish himself over there and come back and get a rematch over here with Wladimir or fight Vitali.
"He is still the most exciting heavyweight in the division. I am proud to call him a friend and I think if he does come back we will get right behind him."
