#6 Dustin Rhodes (as Goldust in WWE) vs. CM Punk
CM Punk was also involved in a few matches with Dustin Rhodes, who went by the ring name Goldust in WWE, albeit them being tag team matches. Punk wrestled with Goldust a few times in multi-man matches in WWE, but they never went up against each other in a singles match.
Their matches together came in 2013, when Goldust and Cody Rhodes teamed up with CM Punk to face The Shield on one occasion.
#5 Cody Rhodes vs. CM Punk
Cody Rhodes has faced CM Punk on a number of occasions in WWE, both in singles and tag team matches. They had even teamed together a few times in WWE.
The two even battled for the WWE World Tag Team titles back in 2008, when Rhodes teamed up with Ted DiBiase Jr. while CM Punk partnered with Kofi Kingston.
Punk and Kofi defeated Cody and DiBiase on RAW in 2008 to win the World Tag Team titles - Punk's only tag team title in his WWE run.
A matchup between Cody Rhodes and CM Punk is yet another mouthwatering prospect in AEW.
