#2 The Club vs Undisputed Era
Recently, AJ Styles turned heel on an episode of Monday Night Raw and reformed The Club, along with The Good Brothers Luke Gallows and Karl Anderson. Styles went on to defeat Ricochet for the United States Title at Extreme Rules, with help from his lackeys.
It seems like The Club is destined to rule Monday nights from this point on, but there's a certain foursome that is just waiting to come up and snatch the spot from The Club.

NXT's Undisputed Era is possibly the most popular faction in the developmental territory. Recently, AJ Styles responded to a fan tweet, that claimed Undisputed Era is another faction that matters, along with The Club. Styles sent a laughing smiley, to which Adam Cole responded by telling AJ to be careful what he wishes for. It seems like we just might see these two groups collide in the near future, possibly in a War Games match. Hopefully, Styles gets a fourth member by that time.
