WBA junior welterweight champion Amir Khan is already planning the remainder of his career. The British star is taking the first step of his "four year" strategy by facing IBF champion Zab Judah in a unification bout on July 23 at the Mandalay Bay in Las Vegas. Khan wants to retire by age 28.

He wants to beat Judah, and then face WBO/WBC champion Timothy Bradley. Should he beat Bradley, he wants to become a pound for pound boxer by fighting Floyd Mayweather Jr. The Mayweather clash has been discussed for the fall of next year.

"I want to break all records and 28 will be a good age to go. I'm 24 now. I won the world title at 22, I'll grab the IBF belt when I beat Judah and I want the WBO and WBC straps as well. Then I want to move up to welterweight and win world titles. The aim is to be the best pound-for-pound fighter. I'm sure I can do that by the time I'm 28," Khan told The Sun.
