10. Sara Del Rey & Cesaro
Perhaps a surprising couple to start off with, Cesaro and Sara Del Rey have known one another for years, meeting outside WWE when both worked as independent wrestlers for companies such as Ring Of Honor. The name Cesaro will be familiar with wrestling fans, and some will even remember him as Claudio Castagnoli, but Del Rey might not be quite so recognisable. Regarded as one of the premier female wrestlers in the world, Del Rey has worked in Japan, Mexico and Europe, as well as North America, and is currently employed by WWE as a head-trainer for female talent in NXT. For those who have seen her wrestle, this is undoubtedly a smart move by the company - Del Rey is vastly experienced, and can parlay that experience onto newcomers, which will only benefit WWE in the long run. Cesaro himself is highly-regarded, but has yet to really hit top gear in WWE. If the company does fully get behind him, the man has all the tools to be a top star for years.
