The American appeared on the latest episode of The MMA Hour ahead of his eagerly anticipated comeback this weekend.
Garcia makes his boxing return against Emmanuel Tagoe at the Alamodome in San Antonio on Saturday night.
Much of the build-up to the fight has been dominated by Garcia’s shocking decision to leave Canelo Alvarez‘s trainer Eddy Reynoso in San Diego.
Garcia, 24, has spoken openly about his battle with depression in the past.
But Canelo claimed Garcia’s recent struggles were self-inflicted due to a lack of discipline.
However, he insisted that this isn’t the case in the slightest.
Asked if the criticism had affected him he said: “No, I know that I’m insane, I’m a maniac from how I work and how I’ve always worked throughout my whole career, so none of that affected me.
“It was just kind of shocking because he knows what I was going through so there was the reasoning why I wasn’t at the gym and that’s why I decided to take a break from everything and make sure I get myself right.
“It had nothing to do with my work ethic and you’re going to see that April 9, how hard I actually work.
“You’ve seen my body, you’ve seen how I fight, you don’t get like that by not working hard, that’s for sure.
“I was more confused and shocked because I know he’s not oblivious and he understands a lot of things.
“So I didn’t quite understand why he would say that, but I don’t really care anymore.”
Garcia also revealed that he hopes his new partnership with head coach Joe Goossen will be the start of something big.
He added: “Goossen, me and him worked together before when I was 17 and when I remembered that I was like, you know what, we had a great relationship and he has an old soul too himself.
“He’s like an old school trainer and I like that feel to the gym.
“I like old music, I like to watch Sugar Ray Robinson so everything just felt good about that decision and once we started working together again it just felt like where exactly I needed to be and we work together so good.
“Our communication in the ring and outside the ring is amazing, our chemistry.
“You’re gonna see that all come together.
“I feel like this is gonna be a long relationship and there’s gonna be a lot of great moments.”
