#4 Samoa Joe
Samoa Joe's clashes with AJ Styles in the TNA ring are the stuff of wrestling legend, but incredibly the pair are yet to meet in singles competition in WWE, having been on opposite brands for most of their time on the main roster.
However, that may change pretty soon. Having been moved over to SmackDown in this year's Superstar Shake-Up, Joe is perfectly placed to make a run at AJ's WWE Championship, especially after Rusev's challenge fell by the wayside at Extreme Rules.
If and when they do get in the ring together, a wrestling clinic is virtually guaranteed. It's just a shame that Christopher Daniels isn't around to recreate that amazing triple threat from Unbreakable 2005.
