A few days ago, Amir Khan hit back at undefeated pound for pound king Floyd Mayweather Jr and branded him "childish" and believes the American star will not be remembered as a great fighter.

The two-time world champion has once again been frustrated in his efforts to land a fight with Mayweather, who instead selected Andre Berto for his 49th bout in Las Vegas on September 12.

During a press conference to announce the Berto fight, Mayweather was asked about his reluctance to battle Khan and suggested that Khan could earn a shot if he avenges his 2012 stoppage defeat by Danny Garcia.

Richard Damerell of Sky Sports in Britain reported that Khan believes a fight with Pacquiao would be easier to make, because the eight division world champion would accept the challenge.

Khan said - "If he’s not going to man up and fight me, then I’ll have to fight Manny Pacquiao or someone like that. Someone who would fight me."

Khan expects to return to the ring in late November or December and still has plenty of exciting options to consider.

Khan met with Pacquiao earlier this year in London and the two boxers discussed a possible showdown.

"I really believe that fight can be made quite easily. I think Manny is a man and he would definitely take the fight."

Top Rank promoter Bob Arum who has been eager to stage a big fight card in Dubai has spoken about a possible Pacquiao-Khan showdown in the United Arab Emirates where there is a huge Filipino community and thousands of ex-pats working in Dubai.
