#1 30-man Royal Rumble match for a world championship match at WrestleMania 35

Major Superstars like John Cena, Drew McIntyre, and Seth Rollins have already announced their entry into this year's 30-man Royal Rumble match, and also they are regarded as the early favorites to win the match. Many more superstars are expected to be added to the match in the coming weeks on Raw and Smackdown.
The results of both the World Championship matches at the Royal Rumble are going to play a huge role in deciding the winner of this Royal Rumble match. Both the current champions Daniel Bryan and Brock Lesnar are widely expected to retain their respective championships at the event.
Right now no one on Smackdown live seems a credible contender to win the Royal Rumble match so the winner is likely to emerge from Monday Night Raw. Seth Rollins is the overwhelming favorite to win the match given the current booking direction on Raw.
If Brock Lesnar is still the Universal Champion after Royal Rumble then Seth Rollins will in all likelihood be the victor else if WWE springs a surprise and books Braun Strowman to win the Universal Championship then Drew McIntyre may be the strong contender to win the rumble.
Finn Balor and John Cena are the next possible contenders in case the above-mentioned superstars fail to win.
Prediction - Seth Rollins wins the Royal Rumble match and earns himself a World championship match opportunity at Wrestlemania 35
