5: Matt Riddle

The recent acquisition of Matt Riddle by the WWE has grabbed headlines throughout the wrestling industry, and what better way to showcase the former UFC star's talents than to put him in a title match with two of NXT's finest performers.
Riddle's place in the match could be kept a secret until the very last minute, with his arrival likely to get a huge pop from the Brooklyn crowd.

The issue would be that the third man is likely to eat the pinfall in this match, with the WWE wanting to save the final showdown between Ciampa and Gargano until a later day.
Having Riddle lose his first match in the company, even if it is in a Takeover main event, is not going to kickstart his career in the way that many fans are expecting.
