Amir Khan compares his fight against Canelo Alvarez to Leonard-Hagler

Looking ahead to his May 7th clash against Canelo Alvarez, Amir Khan believes that this bout will define his career and will become his greatest boxing achievement, despite having already won an Olympic medal and two world titles.

"It's going to be amazing to be called the middleweight world champion and that's like a dream come true," Khan told Sky Sports.

"Even though I achieved a lot in my amateur days and went to the Olympics and also as a professional becoming a two-weight world champion, I still think winning this fight against such a big name in Canelo, and becoming the middleweight champion, will be bigger than anything I've done."

Khan even goes so far as to liken himself to Sugar Ray Leonard when he moved up two weight classes to face 'Marvelous' Marvin Hagler nearly 30 years ago.

"He was in a very similar position to me, where people were saying he was going to get beaten up, get knocked out and get hurt. He was going up two divisions and he went in there and beat Marvin Hagler.

"Sugar Ray Leonard was a great, great fighter but I really believe this is going to take me to up to another level."

Thus far Khan has spent significant time trying to bulk up during training camp, even implementing a pilates regiment to leave no stone unturned in his quest for greatness. We'll see if all the hard work pays dividends come early May. As for the Sugar Ray comparison, Khan is definitely on another level -- just maybe not a higher one.
