During his time in the WWE, John Cena has been loved and hated by the WWE Universe at the same time. Most people will recognise the chants 'Let's go Cena, Cena sucks' as one way which the fans express their opinion about the 15-time World Champion.
Some have even gone as far as suggesting one way which Cena can reconnect himself with all of the fan audience is to have a heel turn for the first time since he was the Doctor of Thuganomics during his rise to superstardom and the top of the WWE in the early 2000s.
A Cena heel turn has been largely discussed amongst fans for quite some time, and every now and then, the man himself teases about a possible change either on WWE programming through his promos, or on his social media accounts.

After announcing he would be returning to the WWE on Memorial Day - May 30 - ahead of his recovery schedule, the former United States Champion joked about turning heel upon his return to the ring on his Twitter account.
He tweeted: "Ok interweb, ponder this, I was hurt. Upon return to @WWE I'll be healthy. So @WWEUniverse does that mean I've finally turned #heal ?"

To be fair, it's a brilliant joke and he does have a valid point, although it's not quite the heel - or heal - turn the WWE Universe was expecting from him.
Storylines upon his return
Cena also announced on his Twitter recently that he would be returning to the WWE on Memorial Day after being out for five months with a shoulder injury. This is ahead of his original scheduled recovery time of nine months. Super Cena is alive and well.
He tweeted: "They said the surgery recovery time is 9 months, but I’m ready to go in 5. This #MemorialDay Cena is back on #Raw. #NeverGiveUp"
So what kind of storylines could Cena be involved in upon his return to the WWE ring?
It has been heavily speculated that the 39-year-old could be involved in a feud with the recently crowned WWE World Heavyweight Champion Roman Reigns at SummerSlam, as he looks to pursue his 16th World title.
If Cena was to win the WWE title at the company's second biggest pay-per-view of the year, he would tie himself with Ric Flair's record of the most World titles ever won by a superstar in history as recognised by the WWE. A record he is rumored to break before he retires from the business.
He has also been rumored recently to be involved in a Legends vs Legends match against The Undertaker at WrestleMania 33 next year in Orlando. The WWE could start building towards this bout soon if the rumors are true in order to give the clash the hype it deserves, as it could very well be The Phenom's last match before retirement.
