#1 AJ Styles
AJ Styles is undoubtedly a dream opponent for Punk, as he is number one in this list. Styles is one of the biggest superstars of the blue brand, and he is having a good feud with Daniel Bryan. However, Styles and Punk locked horns before when they were in ROH, but it will have a different significance in WWE.
Styles is a veteran in the ring and he is regarded as one of the best wrestlers in the world. Styles wrestled in various promotions before WWE signed him in 2016 and he has achieved plenty of success in WWE.
Styles won the WWE title twice and the US title twice. His last WWE title run was astonishing, and he held the title 371 days which was the eight longest world title reign in recent history. He has given numerous outstanding matches in his WWE career.
It will be a treat for the WWE Universe if the two eminent superstars face each other in the future. The match will be worthy to headline WrestleMania.
