#4 Aleister Black
This is a little controversial, mainly because the two superstars in question are on completely different brands within the WWE, with Rousey on RAW and Black on NXT. However, the main reason this match would be a must watch is, unlike the previous pick, will be because of the technical ability and powerful blows.
Both Rousey and Aleister Black have backgrounds in MMA, Rousey being a former UFC Bantamweight champion and Aleister Black having extended experience in kickboxing and an Indonesian form of martial arts known as Pencak Silat. For this reason, the match will be an absolute beauty.

Rousey would be the hard-hitting and aggressive attacker, who would be attempting to push Black into a corner, and Black would be going with a tactic of mind games with his calm demeanor, all the while putting in some brutal kicks.
In fact, one of the only reasons this match wouldn't be a must watch would be poor storytelling, mainly because they have no other connection apart from their backgrounds in MMA.
