The irony of that statement is that Goldberg seems so desperate for relevancy at this point that he most likely will come back to do a Wrestlemania job for Ryback.
LOL it's quite the opposite. Ryback realized that he will never get rid off the Goldberg chants and that he will always be called a Goldberg rip-off so he needs to mention Goldberg very often and how he wants him in the ring.
Goldberg on the other side makes only short replies to the Ryback garbage.
If Goldberg is so desperate he wouldn't say that he only wants big names like Stone Cold or Undertaker in the ring, he wouldn't be missed for 10 years in a wrestling ring
