In an interview with the WWE Magazine, Dolph Ziggler revealed what is holding him back in WWE and which superstar pushes him to keep improving.

On what holds him back: "I don't listen, to a point where if I think something's right, I'll go ahead and do it anyway, and it'll be the wrong thing to do. That's what's holding me back. I tell myself how great I am, but sometimes I'm wrong. Some people have been here a lot longer, and sometimes they're going to be right, and damn it, I'm going to have to pay attention to that."

On which wrestler forces him to keep improving: "No matter who's champ, he's the franchise. When you're out there with him, it's a different kind of ballgame. We are two opposite people and I can't say that enough, and sometimes I hate his guts so much that even when I'm at home, I want to beat him up. We do not see things the same way, but we both have the same goal."
