5 WWE Superstars who could retire after WrestleMania 36

#1 John Cena

When John Cena recently returned to SmackDown and made his speech, it felt like he was finally going to call it quits, but he was interrupted by The Fiend. The Fiend and Cena will face off at WrestleMania 36, in what will be the latter's first match in WWE in over a year.

Cena has time and again spoken about how he is on the verge of calling it quits, although he did reveal that he will be involved with the WWE forever.

“When do I walk away with a sense of mental and physical sanity? I’m right at that precipice. I feel great, I’m in the best shape of my life. It’s not that I couldn’t continue, but I think from this point on I run the risk of tipping that balance the wrong way," said Cena in an interview last year.

The 16-time world champion may well have his final match at WrestleMania 36 as he has achieved everything there is to achieve in the WWE. The Fiend winning would help his character get some much-needed momentum once again after that shocking loss against Goldberg.
