Following his surprise return at SummerSlam, here are three opponents Brock Lesnar must face if he is back in WWE for the long haul.

Cody Rhodes is once again undisputed WWE champion. Rhodes outlasted John Cena in a lengthy, hard-fought SummerSlam Night 2 main event on Sunday to regain the championship he lost to Cena at WrestleMania. But it was Brock Lesnar's return to WWE after the main event that will be the main talking point for many.

Brock Lesnar made his return to WWE on Sunday night, confronting John Cena to close out Summerslam in one of the most disgusting decisions the wrestling giant has made in recent years. It underscores that when it comes to Triple H, the apple doesn’t fall far from Vince McMahon’s tree.
