#1 Brock Lesnar wins clean
The most obvious choice! Not only in this match, but in any match involving Lesnar. He is one of the biggest draws in WWE right now and this is the reason why they manage to re-sign him everytime it is rumoured that he is leaving the company.
He has arguably been the most protected WWE superstar in history and any Brock Lesnar defeat is a big news. Given how Vince McMahon values RAW and the Universal Championship more than Smackdown and the WWE championship, it seems highly unlikely that he will book anything less than a Lesnar victory.
And given the manner Lesnar squashed Strowman recently, who by every means is one of the top stars on the red brand, all signs point to another clean Lesnar victory, possibly after a hard-fought encounter similar to the one between the two men at Survivor Series 2017.
