#6. WWE Free Agent John Cena
John Cena hasn't hinted at a WWE return after his infamous cinematic match against Bray Wyatt at WrestleMania 36. He is currently listed as an unassigned superstar or a free agent on WWE's roster list.
In August, Drew McIntyre spoke to The Sun. He said the following when it came to a potential match against John Cena:
"I want that name on my list. It'd be a heck of a match."
John Cena and Drew McIntyre have never faced each other in a one-on-one match for WWE.
#5. WWE Free Agent Edge
During the Greatest Wrestling Match Ever against Randy Orton at WWE Backlash, Edge suffered a tricep injury.
While Edge is still preparing to make a comeback, Orton is currently embroiled in a feud with WWE Champion, Drew McIntyre.
Speaking exclusively with Sportskeeda back in June, McIntyre revealed that a match against Edge is something he's definitely ready to have from a physical and mental standpoint.
If Randy Orton manages to become the new WWE Champion sooner rather than later, a Triple Threat Match between Orton, McIntyre, and Edge could happen if the Rated-R Superstar returns ahead of WrestleMania 37.
