Gennady Golovkin has thrown down a direct challenge to newly-crowned WBC world middleweight champion Saul 'Canelo' Alvarez.
Golovkin (34-0-KO31) holds the WBA Super, IBF and WBC (interim) belts and has already made an offer to Britain's latest world champion - WBO title holder Billy Joe Saunders.
But with Saunders considering other options, Golovkin has made it clear he is equally keen to face Mexico's Alvarez (46-1-1-KO32), whose only career defeat came at the hands of Floyd Mayweather in September 2013.
Canelo wants to fight everyone, he wants to fight GGG. That fight will be seen by everybody. It will happen.
On Monday, the WBC released a statement on social media that read: "@Canelo wants to fight everyone, he wants to fight GGG. That fight will be seen by everybody. It will happen."
Golovkin replied simply: "Then let's do this @Canelo why wait?"
The Kazakh had previously said via his own social media page: "One of us wants #allthebelts in 2016, so who's it going to be? @Canelo, @bjsaunders #whosnext."
Golovkin was last in action in October, when he seized the IBF crown from David Lemieux with an eighth-round stoppage.
Alvarez won the WBC title the following month when he beat legendary Puerto Rican Miguel Cotto via a comfortable points decision.
