#1 AJ Styles versus The Undertaker rematch

Does anyone else feel like WWE is hinting at a rematch? While many may think the answer to that question is a resounding no, The Undertaker's presence was felt various times throughout the Money in the Bank pay per view. AJ Styles was even caught watching The Last Ride documentary backstage with a bag of popcorn during RAW, which seems like a continuation of the company's rematch hints.
Interestingly enough, Bryan Alvarez from the Wrestling Observer reported that WWE is at least considering the idea of a second-round between them inside the squared circle. If true, that gives a level of gravity to the company's hints for them to meet soon.

However, the company already has Randy Orton and Edge's rematch at Backlash, which likely means it won't happen there. WWE is most likely going to save something of this magnitude for SummerSlam later this year, but the build-up to this rematch should be interesting to see.
