#4 Roman Reigns vs Brock Lesnar
Roman Reigns set his eyes on Brock Lesnar's Universal Championship after winning the first ever 7-man Elimination Chamber match way back in February. The Beast and the Big Dog clashed at the WrestleMania PPV which saw Brock retain the title to end the Show of Shows in a shocking manner. All the fans expected Roman to walk out as the new Universal Champion due to Lesnar's UFC deal but the WWE managed to take them back.
However, when the WWE announced a Steel Cage match between the two for the Greatest Royal Rumble show, once again the fans smelt a Reigns victory but Lesnar retained the belt in a controversial manner. Roman Reigns finally won the championship 4 months later at SummerSlam amidst huge cheers, as the fans were relieved of a part-time champion. This feud established Roman Reigns as the top guy of the WWE as his fiery shoot type promos got him over with the crowd.
