According to the Wrestling Observer and the Inquisitir, Styles has developed some backstage heat, but it’s not being disclosed as of now what he’s done or didn’t do to get that heat.
AJ Styles is the biggest free agent signing in recent WWE history. Honestly, he may be the biggest known free agent signing the company has ever had. It’s very possible that Styles came in with expectations about what he should be doing, and maybe the conflict is over what kind of role he is going to have on the WWE roster.
So far on WWE television, Styles has been feuding with Chris Jericho and The Miz. There are some conflicting rumors about what WWE has planned for him for “Fastlane” and for Wrestlemania in a few months. WWE could push Jericho vs. Styles, develop a feud with Kevin Owens, or continue the feud with The Miz through “Fastlane”
But, it’s very likely that the potential friction between Styles and WWE officials has to do with how he is being booked. Another possibility is Styles hasn’t been easy to work with for a number of reasons. It could just be a rumor, but if the heat is bad, we’ll get more details soon.
