5 challengers for WWE Universal Champion Seth Rollins after Brock Lesnar

#4: AJ Styles

Styles and Rollins faced off at Money in the Bank, though the feud is far from over.

AJ Styles and Seth Rollins have already faced off once before for the Universal Championship, with Rollins retaining the gold against the Phenomenal One at the recent Money in the Bank event.

And though the arrival of Lesnar has disrupted everything in WWE recently, there are plenty of fans hoping for another bout between the two.

With a feud that was built which so much vigour as the one between AJ and Rollins, it seems highly unlikely that the company would have it end so quickly after just one match on a pay per view outside the big four.

There's no reason why these two can't rekindle their feud after Lesnar, with a rematch at this year's Summerslam, complete with possible Styles heel-turn and re-aligning with Gallows and Anderson being just some of the outcomes.
