#3 Charlotte Vs Asuka
Nothing would get Asuka's main roster run back on track faster then a win against Charlotte and Summerslam and that's exactly why WWE needs to do it. It also gives The WWE Universe a chance to see Charlotte versus Asuka part two, which could be one of the biggest selling points for the show if promoted right
With that being said, some might not find Asuka a worthy opponent, especially after her losing streak lately, but it would arguably be the one way to get her career back on track. It also sets Asuka and Charlotte both up to be title contenders and Charlotte would lose nothing by taking a clean loss to Asuka.
In the end, Charlotte is established enough of a superstar that she wouldn't lose any momentum in a situation like this. Not only that, it woudl also be the perfect book end to Asuka's terrible booking over the last few months and would finally make her look like a true title contender again!
