#1 Daniel Bryan
Daniel Bryan is possibly the best technical wrestler in the history of WWE. His journey from being a rookie in NXT to winning the WWE World Heavyweight Championship at WrestleMania XXX was inspiring and loved by the fans. He was forced to retire in 2016 due to medical issues. After two years of struggle, Bryan was formally cleared to return to in-ring competition, making it the best comeback story ever.
What better way to bring Bryan back into the squared circle than to feud him with his arch nemesis, The Authority. Bryan and Triple H have had a long-lasting rivalry, with The Game always playing mind games with The YES! Man at every opportunity he got. Whether it was calling him a B+ Wrestler or getting rid of him as the WWE Champion at SummerSlam 2013, Triple H has never shied away from belittling Bryan.
Triple H may be nearing his retirement, and his last feud with Daniel Bryan makes perfect sense. Bryan being the top fan-favourite performer today, seems like the best candidate to end Triple H's career. Something like this might go as one of the best "faces vs heels" matches.
