Former world champion Amir Khan (31-4, 19 KOs) is setting his sights on all of the big names in the welterweight division.

The weight class is currently packed with a lot of names and a lot of talent.

In a few months, the division will become a little more crowded when Terence Crawford (32-0, 23 KOs) makes his anticipated debut at the weight.

Crawford, regarded as one of the best pound-for-pound fighters in the sport, capped off a huge 2017 after becoming the first boxer to unify all four of the major sanctioning body titles since 2004, when Bernard Hopkins accomplished the feat at middleweight.

Crawford knocked out Julius Indongo in three rounds to unify the WBO, WBA, IBF, WBC junior welterweight titles.

Not long after, Crawford announced that he was planning to vacate all four of his titles for a jump to the welterweight division.

And his debut at the weight will take place on April 21 at the T-Mobile Arena in Las Vegas, when he challenges Jeff Horn for the WBO welterweight title.

Coincidentally, Khan is snapping a two-year layoff - also on April 21, when he faces an opponent to be announced at Echo Arena in Liverpool.

Khan is impressed with Crawford, but he's not fully convinced that the former two-division champion will carry his power to the new weight.

"I think he's a brilliant fighter. He's got a great boxing style. He's more of a boxer, but he can fight as well. Has power in both hands, but he's moved up in weight to 147 [pounds], so I don't know if he's going to carry the same power with him," Khan told Sky Sports.

"I know he was very strong at 135, then he went to 140, but now at 147 is he really going to carry that weight? Not many fighters can do that. Manny Pacquiao carried the power when he moved up in weight, but can Terence Crawford do the same thing? He's got the height and the reach."
