Who do you think would be the next boxing stars and why?

There are several great boxers nowadays but we can see that some of them are a notch ahead against other boxers in skills and popularity. Some of these boxing stars I can mention are Pacquaio and Mayweather. In the past we have lots of them like Muhammad Ali, Foreman, Sugar Ray Leonard, Mike Tyson and the likes. Now if we talk about the present moment, besides Pacquaio and Mayweather who do you think are other boxers that would follow these special groups of boxers that I have just mentioned?
