Gennady "GGG" Golovkin has no plans to hang up his boxing gloves after his trilogy fight with Canelo Alvarez ... telling TMZ Sports he's "not ready" to retire yet.
In fact, the star pugilist said he'd straight up be down to fight Alvarez for a fourth time!
The news is somewhat surprising -- most thought the 40-year-old would call it a career after he takes on Canelo in September for the third time since 2017.
And, watch the clip, you can tell Golovkin has certainly considered it. But, he says he's still got more gas left in the tank despite having fought in 44 pro fights in his career.
"Not yet," GGG tells us about retirement. "I'm not ready yet."
As for why he'd come back to the ring to take on Canelo for a fourth time as opposed to callin' it a career ... he said that choice is very simple.
"The business side," he said, "it's very interesting."
For now, the 42-1-1 boxer says he's happy his fans want to see him in the ring with the Mexican boxer again -- and he tells us he's going for a KO in the match.
The fight goes down Sept. 17 on DAZN ... getcha popcorn ready.
