The Royal Rumble is one of the biggest PLEs in WWE history. The first event took place in 1988, but the inaugural event on PPV was in 1989. However, the Royal Rumble match is one of the most important matches of the year as the winner books their place in a coveted world championship match at WrestleMania.

Sami Zayn has never won a world championship in WWE.

We haven't seen Roman Reigns or Brock Lesnar since Survivor Series: WarGames in November, but both must factor prominently into the WWE's plans for WrestleMania 42.
