Nobody wants to see a Mayweather vs. Pacquiao rematch ... so says boxing superstar Gennady Golovkin who says if Floyd wants to come back, he should call GGG instead.

"I am ready to fight anybody. I am champion. I'm ready for big drama show. [I would rather fight] Floyd [than Canelo]. [Mayweather-Pacquiao rematch], this is not interesting for people. People watch first fight [and it was boring]," Golovkin said.

And with rumblings of Floyd coming out of retirement for one last fight, GGG says it would be a huge mistake for Floyd to fight Manny again ... since the first fight was such a dud.

Gennady fights this weekend against undefeated Dominic Wade -- but everyone wants to know who GGG will fight next ... especially with talk of a superfight with Canelo Alvarez.

Check out the clip ... GGG says he's ready for C.A. ... but if he had to choose, he'd fight Mayweather in a heartbeat.

Make sure to watch the ENTIRE interview with GGG tonight on "TMZ Sports" on FS1.
