Ricky Hatton will be trained by Floyd Mayweather snr for his fight against IBF light-welterweight champion Paulie Malignaggi in Las Vegas on 22 November.
The American, father to Floyd junior - Hatton's conqueror last year, will fly into Manchester later this month to oversee training.
Mayweather will be assisted by close friend Lee Beard, who has been a key member of Team Hatton for more than year.
The Malignaggi fight will be the first of Hatton's professional career without former trainer Billy Graham, with whom he parted company last month.
Mayweather snr, 55, is arguably the world's number one trainer, having previously been in the corner for his son, Oscar de la Hoya, Joan Guzman and current WBC light-heavyweight champion Chad Dawson.
Hatton said was looking forward to working with Mayweather snr and utilising his vast experience.
"At this stage of my career I am not going to change my style too much but you are never too old to learn," said the Manchester fighter, who began his training camp for the Malignaggi bout yesterday at a purpose-built gym at the Village Hotel in Ashton-under-Lyne.
"I have spoken with my team and we are all sure that I'll benefit from Floyd's incredible knowledge.
"The fight against Malignaggi is make or break and I'm convinced this will be the best training camp I have ever had.
"I can't thank the Village Hotel enough for all the help they have given me and it is fantastic they are backing a local lad in his quest to become the world's top pound-for-pound fighter."
The 29-year-old Hatton and his team will fly to Las Vegas at the end of next week for a press conference with Malignaggi at the MGM Grand on 13 September.
