The Argentine, who clashes with Brook at Sheffield's Motorpoint Arena on October 11, expressed his unhappiness at a perceived lack of respect after Brook discussed a potential fight with Amir Khan.
"Once I get in the ring, I will beat the shit out of him," fumed Saldivia.
"I'm going to teach him respect because I'm coming to Sheffield with a simple strategy – to beat the shit out of him.
"Brook will never get the opportunity to fight Amir Khan."
The pair will meet as a welterweight IBF final eliminator.
