#5 To challenge the Undertaker for a final match at WrestleMania 35

The Undertaker and John Cena are regarded as two of the greatest professional wrestlers that ever graced the squared circle.
While Vince McMahon did give us the match we all yearned to see for the last ten years, the match eventually ended up being a squash match at the Show of Shows.
The Phenom squashing the Cenation Leader became one of the most underwhelming aspects of WrestleMania 34 which could make things interesting for next year's visual extravaganza.
There's no denying that John Cena might be looking to close the curtain on his remarkable career at the Grandest Stage of Them All and locking horns with the Undertaker seems like a genuine possibility.
In what could be a solid way to end both their careers, booking a Career Vs. Career match at WrestleMania 35 would make things more compelling for the WWE.
