It has become increasingly easy for Chael Sonnen to acquire fights on the basis of provocation. The victim this time is “The Axe Murderer” Wanderlei Silva, who has said in the past that he does not have much patience for the “loudmouth.”

Wanting to promote a fight against the Brazilian, Sonnen went back to using his Twitter to subpoena Silva and this time gave a deadline for accepting a fight.

With a background screen already showing a possible sign of the scheduled match-up between them, Sonnen posted the following:

Wand- you have 24 hours to accept. If you do, I will donate 10% of my purse to help schools in your hometown of Curitiba .. I mean, VEGAS.

This is a typical approach for Sonnen, who often picks fights with Brazilian fighters who take up residence in the United States.
