5 Ways Dean Ambrose Could Return to the WWE 

#2 Feud with Roman Reigns for the Universal Title

Reigns and Ambrose have never had an extended feud in the WWE

The last remaining feud between the former Shield members that we haven't seen is Dean Ambrose vs Roman Reigns. The two men have met once before on PPV, in the finals of the WWE World Heavyweight Championship tournament at Survivor Series 2015, in a match that was won by Reigns.

Reigns is expected to beat Brock Lesnar at SummerSlam for the Universal title, and with Lesnar likely not sticking around to use his rematch clause, Reigns will be in need of a fresh opponent after the event.

While most fans are expecting Reigns to feud with Braun Strowman or Kevin Owens, it would be a nice twist to have Ambrose return at the end of SummerSlam and congratulate Roman, before laying him out in the middle of the ring with a dirty deeds, setting up a feud between the two.
