Bobby Hill said:I doubt he doesn't know English. He works for WWE, an American company plus Rey and the other WWE superstars probably taught him some.
WWE has hired multiple superstars that doesn't speak English before. Heck André the Giant didn't speak English for a hell of a long time and he is the most well known foreign wrestler in WWE history.
I sadly don't see Cara developing mic skills in English good enough to carry a top card feud. He might become a upper mid carder, bringing the pop of the night and Holy shit moments but he won't be the Cena/Orton level that Ziggler seems poised for. Ziggler is praised as the next HBK for petes sake.
