5 WWE Superstars Vince McMahon has been furious with backstage in 2019

#1: Triple H

The Game has been at odds with his father-in-law in 2019.

Triple H may be Vince's son-in-law, but that doesn't mean the King of Kings and WWE COO is immune from his father's wrath. Earlier this year, the pair reportedly had a "backstage falling out" which seemed to stem from the different perspectives and ideas Vince and The Game have for the company.

One report stated that Triple H, who took the reins as COO in 2013 is the "most frustrated person backstage every night”, and with his father-in-law reportedly not bothering to watch the 14-time World Champion's baby NXT, it's easy to see why a falling out between the two happened.

Earlier this year, the King of Kings liked a tweet criticising Vince, suggesting that the recent rating slumps was directly his fault, and though Triple H quickly unliked the tweet, fans couldn't help but notice.
