#1 AJ Styles

After taking on a smaller but skilled wrestler and a larger and not so skilled wrestler, Lars will need to find a balanced wrestler who can be his final rivalry before he moves onto greater things for one of the brands.
AJ Styles was the longest reigning WWE Champion for WWE in recent times and unexpectedly dropped the title to Daniel Bryan on an episode of SmackDown Live.
Styles will be getting his rematch for the title at TLC 2018, but it is unlikely he will regain the championship once again as recent interviews by him have shown that he is content with losing the championship and getting some time off from a hectic schedule.
After he is done chasing the title once more, there is no better man than Styles who Lars can attack to prove his worth on the main roster.
Not only is Styles one of the best wrestlers in WWE, but one of the best men in the industry around the world. A high-profile rivalry between Styles and Lars could be extremely entertaining to watch and could help catapult Lars to the top even if he is unsuccessful in beating the former champion.
Hopefully, this will prove to be the reason he decides to stick with the blue brand and continue on SmackDown Live.
