Gennady Golovkin has laughed off Billy Joe Saunders calling him out, claiming he wants to fight Saul Alvarez next.
The middleweight king puts his WBA Super and IBF titles on the line when he takes on unbeaten Dominic Wade (18-0-KO12) on April 23.
Saunders (23-0-KO12), WBO world champion, has a mandatory deal with Max Bursak in April, but believes "nobody is invincible" and wants to face Golovkin (34-0-KO31) at Wembley Stadium.
But 'GGG' dismissed the idea and said he would rather face the winner of the huge catchweight fight between Alvarez and Amir Khan.
"It's a joke for Billy Joe Saunders to want to face me right after we announced this fight, he's not serious," Golovkin said on worldboxingnews.com.
"I want to fight Canelo and many big fights, big shows, but it's not frustrating for me to face other fighters.
"This is a big opportunity for Dominic Wade, I remember what it was like before I became a champion, I'm sure he's very hungry for this opportunity and will train hard."
However, Saunders believes he can follow in the footsteps of former amateur Great Britain team-mate Tyson Fury.
Fury, who is still waiting for a confirmation date and venue for his rematch, stunned the heavyweight world by out-pointing Wladimir Klitschko last year.
"Now I've become a world champion I've grown in myself and grown in my beliefs," said Saunders.
"Nobody is invincible, you only have to look at Tyson Fury who went over and done Klitschko in his back garden,
"If I could get Golovkin at Wembley Stadium, which would be a massive fight, I'd show the world I can beat the best."
