1: CM Punk
Despite his major success in WWE, the career of CM Punk has forever been tainted, after the controversy between the Second City Savior and the company.
Leaving in 2014, Punk cited contract disputes and claimed that the company knowingly made Punk wrestle whilst ill.
These claims even led to a defamation case being brought against Punk by WWE doctor, Chris Amann, which Punk won.
Over the years, Punk had made it clear he never intends to wrestle again, and certainly not in WWE.
There is still time left for these two to bury the hatchet, but don't expect either man to budge.
