It's for Daniel Bryan to win the 2019 WWE Royal Rumble and to then go on and defeat The Miz for the WWE or Universal Championship at Mania 35.
The odds are 9/1 as of the time of writing.
It isn't something I believe will play out, but - as noted above - I know a few people out there have fantasy booked a scenario where Miz wins the WWE Championship, Daniel Bryan wins the Rumble and the match is booked for Mania with Bryan going over.
What should also be highlighted is the fact that Daniel Bryan and The Miz will compete in a match during October's Australian PPV - Super Showdown - in which the winner will earn a title shot.
The market is found alongside other WrestleMania 35 specials on the Sky Bet website.
