#5 Kenny Omega

Let's rewind the clock to the day AJ Styles' music hit the stage for the first time during Royal Rumble. He received probably the biggest POP of the night when he walked out. If ever, Kenny Omega walks out on the ramp of the WWE arena then the ovation that he is going to get will be second to none.
Without a doubt, right now he's the best wrestler in the world and currently the face of New Japan Pro Wrestling (NJPW) and in so so many ways the solution to the monotony that WWE is facing right now.

Although with the treatment meted out to Shinsuke Nakamura and Finn Balor it would require a lot of persuasions and a lot of freedom creatively for Kenny but with the deep wallets that WWE has you can never say never. And in the current scenario, WWE really needs someone like Kenny to stop the rut they're in.
