#6 Brock Lesnar Vs. The Rock

Since Vince McMahon ideally books feud that are best for business, Brock Lesnar Vs. The Rock could take his billion dollar company by storm.
The Great One is rumoured to return for a major role at WrestleMania 35, and while he could be squaring off against the Big Dog, an ideal possibility would be to clash against the Beast Incarnate.
Considering the fact that Brock Lesnar defeated the Rock and sent him to Hollywood could surely assist the company in booking a classic feud between the two, with the Great One returning back for redemption.
This bout could very well help WWE in selling the entire show and also restrict the possibility of having the Rock Vs. Roman Reigns at the Grandest Stage of Them All.
The former WWE Champion could finally seek redemption and deliver a fantastic 'Legend Vs. Legend' match against Brock Lesnar.
