5 feuds Roman Reigns can have as Universal Champion 

#4 Samoa Joe

Battle of the Samoans

When Samoa Joe made his debut on the main roster he made an impact unlike any other NXT call-up has ever done. He defeated Roman Reigns twice on RAW and the match they had on the very first RAW of the year just shows their in-ring chemistry.

Expect these guys to feud again very soon; because joe certainly deserves another shot at the WWE Universal championship. When 'The Samoan Submachine' and 'The Big Dog' collide, it's going to be a hell of a match.
