Chael Sonnen has made it clear: he wants Wanderlei Silva for his next fight.

Sonnen, who has called out “The Axe Murderer” for several years, took to Twitter late Wednesday night and issued a deadline for the former PRIDE champion to accept his challenge.

Sonnen has constantly referenced Silva’s decision to live and train in the U.S. and not Brazil.

As of now, no response yet from Silva in regards to the challenge. Rumors have the fight going down in August from Boston on the debut FOX Sports 1 card.
