#6 AJ Styles vs. Shinsuke Nakamura

For the first time in a few years, a fresh, popular competitor won the Royal Rumble. It was even better in that it set up a match WWE fans have been wanting for two years when both AJ Styles and Shinsuke Nakamura came into the company.
Why it will be match of the night:
Cody has no chance against John Cena? Details HERE
We already know the kind of performance these two can put together. Moreover, AJ Styles never seems to have a bad match and Shinsuke Nakamura will be motivated to have a good one on this stage and with this opponent. Since the WWE title is at stake, it will be given the time it deserves, though its placement on the card remains in question.
Why it won't be match of the night:
There's no reason why it shouldn't be unless the nature of AJ Styles' rumored injury is more severe than we've been led to believe. Like Asuka and Charlotte though, the match does have the burden of high expectations.
Perhaps it simply can't live up to them. We won't know until it happens, but along with the SmackDown Tag Team title match, this probably has the highest chance of being the match of the night.
