depends on how popular he becomes. He has the potential to be on Pac, ODLH, and Mayweather's level in terms of popularity due to his huge ****stani and british fanbase. If he gets big primetime fights with Mayweather and if he wins. He could and should cash out and retire. Many people here are just jealous they can't retire at 28 years of age.
Because they want their health. I don't take it seriously when fighters say they're about to retire, unless they're old and shitty. DLH was supposed to retire before 30, Hopkins before 40, Jones back in 2003/2004, etc... These retirement plans should be taken less seriously than a Brett Favre retirement plan.
Khan isn't the type of guy to go out on top. I can't see it. Also 4 years seem like a long time when you are young, but it wont be
