#3 John Cena
This is the match that is probably still the heavy favourite going into The Elimination Chamber. History simply proves that John Cena typically comes out on top in these type of situations.
Another clue would be that he only recently won the WWE Championship, after defeating AJ Styles at The Royal Rumble. It’s just hard to believe that they would use Cena as a transitional champion.
I realise that there are a lot of fans who really don't want to see another Cena vs. Orton rematch, especially at Wrestlemania. To be honest, many don't want to see Cena in the main event at Wrestlemania at all, regardless of the opponent.
For whatever reason, the WWE Universe turned on Cena a long time ago. I get it, you’re tired of seeing the same matches, the same superstars and so on. But, it is important to understand that there is a very real possibility that John Cena retains his title at The Chamber, resulting in a date with The Viper.
Personal feelings aside, if this match does, in fact, come to fruition, you can rest assured that both Cena and Orton will deliver a main event calibre performance.
