Robert Whittaker opens up on what caused him to lose to Israel Adesanya at UFC 243

Israel Adesanya captured the UFC middleweight strap from Whittaker by knocking him out in the second round at UFC 243.

In a recent interview on The MMA Hour with Ariel Helwani, Whittaker discussed how his anger played a big part in his non-performance against Adesanya in 2019:

"I got in my own head so much and I had so much grudge towards him and gripe that I wore myself out. I had so much anger and hate, and I wore myself out. It got tiring being angry at him, and for no real reason... You can see how out of the ordinary I fought. How reckless, if you would, how I fought. I guess that’s the biggest regret I would have in that fight. I wish I fought like myself."

Furthermore, Whittaker says the Adesanya loss led to a lot of soul-searching:

"After the first loss, I had a big chunk of soul-searching and trying to understand myself and my own headspace. That kind of set the foundation for everything else I can do."

Meanwhile, the upcoming fight between the top two middleweights will mark Adesanya's fourth title defense. The champion has already beaten Yoel Romero, Paulo Costa and, most recently, Marvin Vettori.
