5 Incredible feuds that must happen after SummerSlam

#3 AJ Styles vs. Randy Orton for the WWE Championship

The biggest babyface vs. the biggest heel

If there's a match on the blue brand that can be a legitimate box office draw, it is AJ Styles vs. Randy Orton for the WWE Championship.

While the fans are totally into the Phenomenal One squaring off against Samoa Joe at SummerSlam, rumors are rife that Styles will retain his WWE Championship at the biggest party of the summer.

Considering the feud will reach its conclusion somewhere in the future, the next ideal opponent for Styles should be Randy Orton.

Orton is bringing the old heel back and the character has more edges and layers this time around, and if everything goes right, then he could eventually take the WWE Champion to his limits.

A feud of this caliber cannot be ignored in any fashion, and since they have already squared off in singles action before, the roles have now reversed and a heel Randy Orton could inject his venom and take the Phenomenal One to ViperVille.
