5 Rivalries still left for John Cena in WWE 

#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.
