#1. Rusev
Rusev has somehow made the most of a rather controversial love triangle storyline and has come out of it as a bigger babyface than before. Despite the nature of the angle that's made many people uncomfortable, there's no denying that Rusev did the best he could to get over.
He's all set to take on Bobby Lashley in what appears to be the culmination of this rivalry. It's a no-brainer that Rusev would top this list because nobody needs the win more than him. We understand that to extend the rivalry, WWE would have Lashley win, but the entire point of the story is for Rusev to come out of it looking great at the end - which means beating Lashley.

Rumors were floating about from WON that Lashley suffered an arm injury recently, which, if true, means that the feud has to end at TLC. There are no two ways about it and there would need to be a post-match angle to write Lashley off TV until he recovers.
For all that Rusev has been through and the way he's made the most out of it, he needs the win more than any WWE Superstar on the roster at TLC 2019.
