While many have won the Rumble and failed to win the title at Mania, almost all have won the world title at some point in their careers. You have to go all the way back to 1994 when Lex Luger was a co-winner of the match with Bret Hart to find the last Rumble winner to never hold a world title.In addition to Nakamura and Luger, the first two winners of the Rumble, Big John Studd, and Jim Duggan never won a world title in WWE either.Could Nakamura win the Rumble again? Could he perhaps finally win the ultimate prize in WWE? In a recent interview, Nakamura said that is still his goal.

He is one of the best in the world. But I need to get the WWE world title. I need to prove I’m better than him. Roman has that fighting spirit.

Like veterans and young people."He continued to say that it seems many Superstars are paired with others in WWE."Even in NXT, it’s like handsome (Jiro) and KUSHIDA.

The deal never came to fruition, however. Still, Nakamura hopes that the two companies could work together. He had the following to say about this to Tokyo Sports:"It’s [NJPW’s] 50th anniversary. I hope that there is something I can do to help them through my company. A match (in NJPW) would be… difficult. But if they really try to negotiate… it might be possible," Nakamura said."Right now, the situation is such that they are probably going to have to quarantine the [wrestlers] and take [border] measures. The risks are still too high. It would be nice if the situation calmed down and if there was a TV show that invited me," he continued.It's possible one day we could see Nakamura return to NJPW, but that does not appear to be something that can happen anytime soon.
