Chuck Liddell says Chael Sonnen's claim that he turned down multiple offers to fight him is complete and utter BS ... and he ain't gonna let it slide.
"I've never been offered a fight with him," Chuck told TMZ Sports. "Never. No one's offered me anything to fight him. Not even a bad deal that I didn't take."
The Iceman says Chael's just up to his old tricks -- churning out fake news -- and he's got a solution to shut him up once and for all.
"He knows where I train at. Come on down! We'll see what he can do."
Probably ain't gonna happen since Sonnen's signed up to fight Rampage Jackson in January ... but it definitely looks like Liddell's prepping for somebody.
