John Cena and The Undertaker are two of the biggest stars in WWE history. But the paths of both men didn't cross often in WWE. Between 2003 and 2006, they only wrestled five singles matches against each other. After that, they didn't have a singles match against each other until their short clash at WrestleMania 34.
Speaking to Connor Casey of Comic Book, Undertaker explained why they didn't work together more when they were both full-time.
"Honestly it was just the booking," he explained. "And that time period when I was still working all the time, we were both babyfaces so you didn't really want to do that. And then it just came down to at the end there, John wanted to work with me and do something and it was fresh. And like I said, at this point in the career, it's hard to come up with fresh matches. It's just difficult because you have to cycle through everybody so many different times, but no there was never really reason why, it was just the way things were booked."
Undertaker worked a full-time schedule until 2010 when Cena was the face of the company from 2006 to 2010.
On the series finale of The Last Ride, Undertaker stated he has no desire to get back into the ring. You can find his full comments by clicking here.
