#2 Andrade
Ever since making his return to WWE, Andrade has been a primary opponent for Rey Mysterio. Both competitors have crossed paths several times, delivering astounding matches every single time. Given the fact that Mysterio is the US Champion now, Andrade could target his former foe once again.
Andrade moved to RAW in the draft, but is yet to get involved in a noteworthy feud. The former NXT Champion faced Sin Cara and Cedric Alexander over the past couple of weeks, building momentum and winning those matches. Andrade didn't participate in Survivor Series, as he failed to beat Seth Rollins on the RAW before the big pay-per-view.
Mysterio wanted to quit two months ago because he suffered an embarrassing loss against Andrade, failing to meet his own expectations. Both men can restart the storyline from there, and it could garner the attention of a myriad of fans. They already produced normal matches, but considering their in-ring proficiency, could tear the house down, if they wrestle with different stipulations. With TLC around the corner, the two high-flyers could offer an incredible Tables, Ladders, and Chairs match.
