#1 Conor McGregor
In the past, Conor McGregor has been quite vocal about WWE and its superstars, especially John Cena, and has hinted a potential career in WWE on several occasions. In fact Triple H, the COO of the WWE, has gone on admit that the company has been keen on signing McGregor for quite some time.
The Notorious One retiring from UFC and signing a contract with WWE in the near future looks unlikely. However, given how he always says 'It's all business', WWE could have him onboard as a guest host at WrestleMania 35 for a huge paycheck.
Given the recent rumours of WWE planning to have Charlotte Flair vs Ronda Rousey as the main event of WrestleMania 35 after Roman's departure, plus Triple H doubtful for his rumoured match against Batista, McGregor's inclusion as the guest host would not only increase the brand value, but would also eliminate any possibility of low attendance.
