Jean Claude has quite an interesting history with Chuck Zito. Chuck basically blasted him one night in a bar after hearing Van Damme said he had no heart. Zito ended up breaking a bone in his hand while Jean escaped unharmed after covering up during the onslaught of punches.
I knew Zito, Van Damm would win! Huge differance in size and athletism,also some friends introduced me to some young guys Zito fought who i found not tough at all,and they fought him to a draw. Zito was the type of guy that was very tough but not so much a polished or fair fight type guy and had just an edge to him that if you werent overly tough you would be in a fight. Im sure he can punch but i dont see him beating a prepared Van Damm.
