The most likely clash on this list (because it's actually happening at Elimination Chamber), but the burgeoning reality of a Cena/Owens feud makes it no less compelling. The pair are polar opposites; Cena is the ultimate clean-cut company man, while Owens made his name as a dangerously unhinged renegade in Ring of Honor. Despite Cena's highly-criticised tendency to win against just about everyone, he's tough enough to take as hard a beating as anybody on the roster. This quality will come in incredibly handy against the menacing Owens, who will surely get himself over at the next PPV by beating the US Champion within an inch of his life (regardless of the match's actual result).
