LAS VEGAS — UFC heavyweight champion Junior dos Santos has become surprisingly fluent in English in a very short period of time, and he used those new language skills to issue some strong words to rival Alistair Overeem in this exclusive interview.

I caught up with Dos Santos to discuss how much his life in Brazil has changed since he won the heavyweight title, what the sport could mean for children growing up in poverty across Brazil, whether or not he thinks Velasquez is playing mind games with him by releasing a video that reportedly shows the former champion injuring his ACL last fall and much more.

As noted above, Dos Santos also has something to say about rival heavyweight Alistair Overeem.
