#4: Shinsuke Nakamura
Shinsuke Nakamura is one of the biggest stars in New Japan Pro Wrestling history
John Cena is one of the biggest stars in WWE history, so a bout between the two is nothing short of a dream-match. Meeting on SmackDown in 2017, the pair met with high stakes on the line, a shot at then WWE Champion Jinder Mahal at Summerslam.

In a war between the two, it was the King of Strong Style who got the upset victory, toppling Cena with a flurry of attacks. Despite this win, Nakamura would come up short against Mahal, who wouldn't lose the title until November to AJ Styles.
Cena and Nakamura would meet once more, at the 2018 Royal Rumble, where the Japanese star would eliminate the 16-time WWE World Champion on route to winning the 30-Man match.
