5 things you need to know before tonight's WWE SmackDown Live (January 1st, 2019)

2: McMahon's fallout after Phenomenal attack

What will McMahon do after getting slapped by the Phenomenal One last week?

Ever since he was drafted to the brand in 2016, AJ Styles has aimed to make SmackDown Live the house that he built.

Impressing in matches for years, AJ's year-long reign as WWE Champion only proved this, before it all came crashing down at the hands of the new Daniel Bryan.

This loss has certainly taken its toll on Styles, who attacked the Chairman, Mr. McMahon last week, when goaded by the Boss.

Its a side of Styles very few have seen him show in WWE, though a reeling McMahon was left with a huge grin after unleashing this darker side of the Phenomenal One.

Now, with SmackDown just hours away, it will be interesting to see what both Styles and the Boss will say after such a shocking turn of events.
