Mediocre pugilist Amir Khan said during Monday night’s Golden Boy telecast that he will make Floyd Mayweather’s “old legs move” if they throw fists.

Khan (28-3, 19 KOs) was tentatively slated to scrap IBF welterweight titlist Devon Alexander this December at the Barclays Centre in Brooklyn.

However, Khan decided to bypass Alexander (25-1, 14 KOs) and instead focus on a potential bout against the 36-year-old Mayweather (45-0, 26 KOs).

“We’re still working on a few things,” said Khan, 26, who at 17 became the youngest Englishman to win an Olympic medal when he captured silver as a lightweight at the 2004 games in Greece. “We were looking at a fight against Alexander. That fell through. There’s a lot of talk about the Mayweather fight happening, but at the moment, I’ve left it up to my team and Golden Boy.”

The Pakistani-British boxer then offered a blueprint to trump Mayweather.

“With Floyd Mayweather, if you’re going to be a puncher, you’re going to walk towards him and you’re going to walk into his shots,” said Khan, who became one of the most youthful British world champs ever at the age of 22. “To fight Floyd Mayweather, you have to box him at his own game. You have to box him. You have to use speed, good footwork, make them old legs move.”

Flattened by a left hook in the fourth and staggered by the same punch in the eighth, 10th and 11th rounds, Khan most recently escaped from the squared circle in April by outscoring Mexican Julio Diaz.

Comparatively, in an utter mismatch, Mayweather earned a majority decision over precocious brawler Saul Alvarez on September 14 to gain the WBC light middleweight crown.

Although the 23-year-old Alvarez (42-1-1, 30 KOs) didn’t perform poorly and consistently forced the action, Mayweather landed flush shots for 36 minutes that flustered and slowed the youngster.

 

Destined to equal Rocky Marciano’s 49-0 mark and retire as an unbeaten titleholder, Mayweather’s a defensive virtuoso and one of the premier prizefighters in history.

In stark contrast to The Ring “Fighter of the Year” in 1998 and 2007, “King Khan” is simply an overrated chandelier.

Expect an unworthy Amir Khan “to walk into” Floyd Mayweather’s punches and get knocked onto Queer Street within eight rounds this May.
