Ricky Hatton believes that Floyd Mayweather's upcoming fight against Saul Alvarez will be the toughest of his career.
The retired British legend is of the opinion that the fight on September 8 between the pound-for-pound king and his fellow unbeaten opponent Alvarez, will be a close contest.
"I do think this is Mayweather's toughest fight," Hatton told the Daily Mail.
"For someone so young Alvarez is very, very talented. He has youth, power, strength and size on Floyd.
"Alvarez has had a lot of fights, but not miles on the clock."
Mexican Alvarez, who boasts a record of 42-0, is Mayweather's most physically powerful opponent to date and is only the American's third fight in the 154Ib division.
Alvarez also has age on his side, with there being a 13-year age gap between the 23-year-old challenger and the 36-year-old Mayweather.
Hatton does believe however, that despite the almost inevitability of a strong challenge being fronted by Alvarez, Mayweather will come away victorious.
Hatton stated: "Despite all that I don't see Mayweather losing to him. His timing, defence and speed will just be good enough to see him over the finishing line.
"The risk against Floyd is that he's 36-years-old and had a lot of fights against some very good men.
"He is coming to an age where fighters get beaten, but because of his wonderful defence he can go on longer than most because he doesn't take stick," the Mancunian added.
Hatton was famously beaten by Mayweather in 2007 in a highly-anticipated contest, and his younger brother, Matthew Hatton, was dispatched by Alvarez in 2011.
