WWE WrestleMania 39: 10 Nightmares That Could Come True

10. The Mysterios Don’t Have Chemistry

...as opponents.

Rey and his boy Dominik definitely had more chemistry than some were willing to give them credit for as a tag-team, but actually working against one another in-ring could be a different story. Both father and son could be in for a rude awakening on the biggest stage possible.

Fan expectancy will be high when the bell rings. This is a Rey Mysterio match at WrestleMania, and there's a lot of chatter doing the rounds that he doesn't have too many of those left. Further, he'll be in there vs. his own flesh and blood, so Rey-Rey will be desperate to make Dom look as good as he can.

Imagine disaster struck and, just a few short minutes into their clash, daddy dearest stared at his rebellious son with a face that screamed, "Sh*t - we don't match up well at all as rivals". That'd be horrible for the whole family, and for the live crowd too.
