WWE SummerSlam 2016: 10 Things That Must Happen

10. John Cena Vs. AJ Styles Opens The Show

The last thing fans witnessed on SmackDown Live this week was John Cena thumping AJ Styles with an Attitude Adjustment through the announce desk. That followed Cena's victory over a game Alberto Del Rio, a match during which AJ ran down his SummerSlam opponent on guest commentary before getting his comeuppance.

It'd be awesome if the first thing fans witnessed on the actual SummerSlam pay-per-view was the showdown between Cena and Styles. The latter has to be out for retribution, the match can't be booked any other way. AJ looked strong on the mic before being blasted by his rival, meaning the bout should be an intense one.

The result of the match is up in the air, it really is anyone's guess. It's unlikely that WWE would book a second clean win for AJ Styles over John Cena on pay-per-view, but stranger things have happened. Meanwhile, Cena doesn't need the win himself.

Whatever the outcome is, it'd be great to see the match as the SummerSlam opener. WWE have a glut of top clashes on the card, so spreading them out might be wise.
