Amir Khan recently expressed his view that Manny Pacquiao would be harder to face compared to Floyd Mayweather Jr. or even Kell Brook.

Khan has earlier expressed his intention to fight all three. Though all of them have scheduled fights within the year, none of them is a fight against him.

According to Sporting World News, Mayweather will be facing Marcos Maidana next month in a rematch. Pacquiao will go against Chris Algieri while Brook will face Shawn porter on Aug. 16. Khan will reportedly fight Robert Guerrero or Devon Alexander this coming December but he initially backed out from any fight plans due to his anticipation of fighting Mayweather.

The Guardian said in a report that it is more possible for Khan to face Brook who is now preparing for a match in the United States. Khan is reportedly not really impressed with Brook but said that he admires him traveling to California to face Shawn Porter.

"I respect that a lot. Not many fighters would go away from home against Porter and, if Kell wins, it would put him straight in the big time. It would then definitely make sense for me and Kell to fight. We saw what Froch and Groves did at Wembley with 80,000 fans. We can also do that. But it's a big step up against Porter. Is he ready? He's been fighting C-class guys and now he's in with an A-class fighter," Khan noted.

He also mentioned in The Guardian article that fighting Pacquiao would be harder than facing Mayweather because the Filipino champ is "more aggressive."

"Boxing is all about timing and Manny and Floyd are getting older. Someone has to take their place. Mayweather would be a very technical fight, like a game of chess. But I think Manny would be harder. He's much more aggressive and it would be more intense. But with my trainer Virgil Hunter I'm a much better and more defensive fighter," he explained.

But Khan openly said that he does not believe that Mayweather will be up for his challenge.

"It's a tough one. I know he needs me to make the really big pay-per-view numbers and money motivates him. It drives him because he can make much more fighting me than Maidana. I'm big in the UK, Dubai, Asia and places where Floyd's not as well known," he was quoted by Sporting World News as saying.

Khan, however, expressed his optimism in fighting Pacquiao seeming a little more excited about it.

"My promoters, Golden Boy, and Bob Arum [Pacquiao's promoter] are about to start working together again. Me and Manny sparred a lot, and I often went with him to the Philippines, so it would make a great fight. I've left it with my team and my adviser Al Haymon [who also works closely with Mayweather] and I told them: 'I like the Manny fight.' But we've had no response," Khan explained.
