#3 John Cena and Randy Orton
John Cena and Randy Orton are perhaps the two best-known wrestlers in the world at present since both came through the ranks in WWE around the same time and have dominated the company for more than a decade.
The fact that Orton was the main heel in WWE at that time and Cena was the main face meant that more often than not a match between these two stars would be the one that would make it to air. Despite seeing their feud numerous times, fans were still invested in it because Orton and Cena knew how to take it to the next level, with Orton even punt kicking Cena's father at one point.
Even though these two stars had a fantastic rivalry on TV, they were seen many times backstage together and Orton's own daughter reportedly thinks of Cena as an uncle. It would be hard for the two men to put on the level of matches that they have over the years without at least becoming friends, so it's interesting to see that they are now both looking at their options after retirement but still quite close outside of the company.
