5 Rivalries still left for John Cena in WWE 

John Cena has emerged as one of the biggest names in the history of professional wrestling. He has been The Franchise for the past 15 years and has emerged as one of the greatest of all time in WWE history.

The 16-time World Champion has crossed paths with most of the Superstars who've performed for the promotion during his 15 years on the main roster. He has fought legends and future stars in his time with the company.

At times, one-off matches between most Superstars in the WWE transpire on a weekly basis—with performers who aren’t exactly involved in a storyline with one another, also facing off inside the ring in randomly booked matchups.

Nevertheless, the fact remains that the WWE and professional wrestling as a whole, works on carefully crafted feuds/rivalries which are played out over the course of several matches. These storylines feature two or more Superstars engaging in a battle for glory—with several elements of drama depicted in the storyline.

Speaking of which, the WWE roster is so very stacked that several dream feuds between top-tier Superstars often slip away without being booked. The current WWE roster boasts many big-name performers—a few of whom have never feuded with certain other Superstars.

On that note, John Cena—perhaps the WWE’s most consistent top Superstar over the past few decades—is yet to face a few marquee names on the current promotional roster.

Cena has defeated many and lost to some. Regardless, there are still a few superstars left on the roster with whom he hasn't feuded over the course of his illustrious career.

Here are five superstars on the main roster whom John Cena hasn't feuded with yet--

#5 John Cena Vs Bobby Roode

Bobby Roode is a veteran in the pro-wrestling business. Before even being in the WWE, he made a name for himself in TNA (now--Impact Wrestling). In WWE, he was great on NXT and SmackDown, however his character hasn't quite clicked since his arrival on the main roster.

Roode presently is one of the most underrated WWE Superstars.

Many may not want this rivalry with Cena, given Roode's current standing in the WWE food chain. However, the rivalry would become interesting if Bobby Roode turns heel on Cena after attacking Cena much like a heel AJ Styles did in 2016.

Roode turning heel and attacking Cena--following which, the two having a decent feud, would most definitely help establish Roode as a legitimate top-tier Superstar in the WWE.

#4 John Cena Vs Braun Strowman

We never saw a rivalry between these two

We have seen them compete in three different matches namely a singles match resulting in a no contest, a triple-threat match won by Elias and inside Elimination Chamber where Braun eliminated John. However, we never saw a full-blown rivalry between these two men.

Rumors indicate Braun will turn heel around WWE SummerSlam. What else could be a better angle for Braun than to fight a returning John Cena in the days following SummerSlam?

Not only it will give us a brand new feud, but also ensure a clear winner in a proper match between the two. It would be nice to see how WWE books it, and one thing is for sure--we are going to get a clear winner this time!

I am afraid that Cena might "Get These Hands".

#3 John Cena Vs "The Scottish Terminator" Drew McIntyre

Drew McIntyre transformed into a beast after leaving WWE in 2014

Drew McIntyre is one of the best talents and characters currently performing on the WWE main roster. He is a true beast and an unstoppable force.

Presently teaming up with Dolph Ziggler, WWE surely has big plans for McIntyre. Both Triple H and Vince McMahon reportedly have high hopes from the Scotsman.

Years ago, Vince McMahon himself labelled Drew as "The Chosen One".

To become one of the best in WWE, McIntyre needs to commence a feud with John Cena. Drew McIntyre hasn't faced John Cena, even during his first run with the company, however if he would have at that time, most believe that Cena would've emerged victorious.

Nevertheless, this time around the scenario will be different. The rivalry between these two would be great and replete with hard-hitting contests.

The WWE Universe will surely look forward to this one.

#2 John Cena Vs Finn Balor

Finn Balor and John Cena have only faced each other on the odd occasion on RAW

Finn Balor is one of the best performers today, and has the potential to be the greatest Superstar in WWE. The first ever WWE Universal Champion has all the tools required to be a top star in WWE, and has shown it in matches against the likes of AJ Styles, Seth Rollins and Braun Strowman.

While John Cena and Finn Balor did face each other in February, the match ended with John Cena beating Finn Balor clean. However, they never entered a proper feud back then.

Balor needs to enter a program with John Cena. Most importantly, a feud between Demon Balor and The Franchise is money. Not only would this feud be a dream come true for many fans, but it shall also undoubtedly help Balor ascend to the top of the heap.

Perhaps it could be a passing of the torch movement with Cena putting Finn Balor over, and raising Balor's hand in a show of respect.

#1 Samoa Joe

A feud for the ages

Is there any bigger opponent left for John Cena in WWE than Samoa Joe.

Samoa Joe is one of the best pro-wrestlers in the world. He and Cena share the same path to success with a slight difference, the companies they signed.

While WWE signed John Cena, TNA signed Samoa Joe which led both of them to stardom. Both of them are now in WWE.

WWE tried to book a rivalry between the two, however, the feud was cut short when Joe unfortunately suffered an injury. While Cena has pinned Joe in a 5-on-5 Traditional Survivor Series, the two never had a singles match.

The fans know that these two will tear the house down if booked in a feud. The idea of this match sounds like promotional gold for the WWE!

The WWE could attempt to book a rivalry between Cena and Joe, only this time with the WWE Championship on the line.

Joe is currently in a feud with AJ Styles for the WWE Championship. Speaking of which, Joe might win the WWE Championship at SummerSlam.

Perhaps a feud between Cena and Joe over the WWE Championship could be on the cards in the near future.
