Israel Adesanya made to regret Alexander Volkanovski comment moments before Islam Makhachev KO

A video shows Israel Adesanya's heartbreaking reaction to Alexander Volkanovski's crushing defeat to Islam Makhachev at UFC 294.

Volkanovski failed in his bid to win the UFC lightweight title as he suffered a brutal knockout defeat on Saturday.

Makhachev executed a vicious head-kick to stop the Australian fighter to defend his UFC crown in the main-event of UFC 294.

Adesanya, who lost the UFC middleweight title in his last outing, watched his teammate in action for his YouTube channel, FREESTYLEBENDER.

And he was made to regret his comment about Volkanovski moment before he was beaten by Makhachev. Check it out below:

"C'mon Volk, let's go," he said. "I believe in him..."

The Dagestan star then inflicted the fight-ending blow.

'The Last Stylebender' added: "It was a left kick from southpaw, but it went over the head - just clipped him.

"I think he caught him with it in the first fight."

The UFC featherweight champion bravely opened up about his mental health problems following his defeat.

He also explained why he wasn't able to 'pull the trigger' in the Octagon.

"I felt strong," he said. "I felt strong in there, but obviously I’ve been telling you I want to put some hands on him and whatnot. I wanted to pull the trigger, but it just felt a little weird in there, that little bit hesitant, which I didn’t expect. It was like I was waiting for something.

"I was like, 'I’m going to go, I’m going to go,' and then he got me."

Volkanovski's UFC 294 outing was his first appearance since July when he defeated Yair Rodriguez.

Despite the knockout loss, he's hoping for a quick turnaround as he eyes a defence of his UFC featherweight title against No.1 contender Ilia Topuria.
