Eddie Alvarez reveals post-fight torment following Conor McGregor knockout at UFC 205

FORMER UFC lightweight champion has revealed his torment following his knockout defeat to at .

Alvarez was knocked down FIVE times en route to a second-round knockout loss at Madison Square Garden as McGregor made history as the UFC’s first simultaneous two-weight world champion.

And the Philadelphia fighter took to his Instagram account to post a message congratulating McGregor and revealing his emotions after losing the biggest fight of his career.

"Congrats to Connor and his camp on an amazing accomplishment,” he wrote.

“These guys continue to deliver, hats off to you fellas.”

Alvarez gave a scathing assessment of his own performance in the fight, saying he went against the gameplan he and his coaches had perfected over a 10-week training camp.

"As for my performance, the only thing I can honestly say was I f*****g blew it,” he admitted.

"I did nothing I trained, I did the complete opposite of what we planned on a daily basis for 10 weeks.

"To sum up our plan in a sentence it was 'Go left and mostly wrestle’. Instead I circled into his left hand and mostly boxed.

"Fighting the way I did was a for sure death sentence and the result was fitting.

"I say it all the time, there is really small margin for error at this level and I paid for my mistakes.”

And the former champ said he now has the job of picking himself up after the biggest disappointment of his career.

"I managed to make it to the biggest stage and audience in my long career and f****d it all up when I arrived,” he said.

“My heart sincerely hurts and when I dwell on it I fill up with regret and anger.

"If there was a list of what not to do against an opponent of this nature I did them all on Saturday.

“I am disappointed in myself and this is not a reflection of my coaches, training partners, and the endless hours of training I commit to this sport.”

‘The Underground King’ said he’s had to lean on his family to help pick him up after his crushing loss in New York, but vowed to return to test himself in the Octagon once again.

"I thought in my head at least making a lot of money would make me happy but I am having a lot of trouble enjoying myself regardless of the check thats going to be written, I am very uneasy and discontent for the most part,” he revealed.

"I am lucky to have my wife and my child at a time like this to help me laugh and smile and let me know everything's gonna be all right, they are my saving grace, without them I am a shell of a man.

";Besides the outcome I thoroughly enjoyed fight week and the lead up, it was a lot fun.

"I have never defined myself off one win and I'll never define myself off one loss, I simply had a bad night.

"I'll have the opportunity again to have a good one, and I'll make the walk to see what I got every time."
