6 superstars who could challenge Shinsuke Nakamura for the US title 

#3: Samoa Joe

Samoa Joe will need something to do following his defeat to AJ Styles

One of the biggest questions coming out of WWE's Super Show-Down event in Australia was surrounding the future for Samoa Joe.

Joe has been on a role in recent months, following his second successive defeat to AJ Styles, it seems highly unlikely that he will be sniffing around the WWE title picture again anytime soon.

Nakamura rebounded from his defeat at the hands of AJ Styles by instantly entering the United States title picture, and with no other top level faces on the brand left for Joe to face off against, that may well be the best option for him as well.

As with Almas, booking a heel vs heel feud could be difficult, but both men's characters rely on them being driven by glory, as opposed to any other sort of motive, so there's no doubt that the WWE could make this work.
