Wanderlei Silva appears to have had enough of Chael Sonnen already, taking to Twitter to call him out.

The two are wrapping up filming for The Ultimate Fighter: Brazil, but that hasn’t stopped the trash-talking.

Last month, they had to be separated after becoming involved in a “fight.” Sonnen recently let it be known that he feels Silva is overweight and trying to get out of their planned fight for later this year.

“The Axe Murderer” decided to make a post, saying, “If you are real Man talk this to me tomorrow, face to face or shut up.”

The season of TUF is scheduled to air on the UFC’s Fight Pass, the first one to be shown on the all-digital platform. They are set to fight at UFC 173 in May.
