#2. Rey Mysterio's unfinished business with Samoa Joe

If there's one word that can best describe Rey Mysterio and Samoa Joe's rivalry - it's animosity. The rivalry between the two veterans has been nothing but vicious and personal, with Mysterio's son Dominick in the backdrop more often than not.
At Money in the Bank, Mysterio not only busted Joe open, but he won the United States Championship in controversial fashion. Joe's shoulders were visibly up from every angle when the referee made the count, yet he blatantly ignored it.
Look who just shut down all of Tony Khan's critics! More HERE.
With Mysterio's unfair title win, Joe was livid and attacked the legendary luchador. It's very evident that business isn't finished between the two stars and they could end up going at it for the United States Championship as soon as tonight.
And we fully expect Samoa Joe to regain the United States Championship just a day after losing it to Mysterio.
