#3 John Cena vs. Samoa Joe
If John Cena is Mr. WWE, there are few wrestlers who could personify TNA more than Samoa Joe.
A former TNA World Champion, Joe joined the WWE in May 2015 and has certainly made a name for himself, holding the NXT Championship twice, and being one of RAW's top Superstars.
With Cena being a free agent, a clash between the two could be coming in 2019, and would certainly make headlines.
The Samoan Submission machine and Big Match John have had very different journeys in wrestling, though no-one can deny their success.
Yet to hold any gold on the main roster, Joe could certainly put himself in contention, if he was able to topple the 16-time World Champion, ideally at a huge pay per view such as WrestleMania or Summerslam.
