#1 John Cena vs Lars Sullivan
Well, the rumours have come true as John Cena will be returning as a free agent to WWE on December 26 2018. And keeping Royal Rumble in mind, expect The Leader Cenation to be in for a long stint.
On another note, Lars Sullivan who was declared a free agent a few weeks ago on Raw is also expected to make his WWE main roster debut anytime soon. Given John Cena has transitioned himself into a part-timer now, plus his reputation of putting over talents, we could be in for a great feud after TLC.
Lars Sullivan has been nothing but impressive in his recent stint with NXT. Often regarded as the next Brock Lesnar, Sullivan feuding with a 16 time WWE Champion upon his debut on the main roster would not only do wonders to his character, but would be 'best for business'.
