WWE star CM Punk has opened up about the various factors that led to his return to WWE, following his acrimonious exit from the promotion over a decade ago.

Surprisingly, for being as big of a name as he is, the 'Chicago-Made Punk' hasn't had many WrestleMania appearances.

A sensational moment occurred at the closing of WWE Raw on April 7 when CM Punk joined forces with comedian Bert Kreischer.

CM Punk says that he learned a lot from Eddie Guerrero, but revealed one key lesson he received by working with the pro wrestling legend and WWE Hall of Famer.
