KSI has laughed at Jessie Vargas after the former world champion told the YouTube boxer he "doesn't know to how to punch".
Vargas, 33, once held the WBO welterweight title but lost the belt in his first defence against former eight-weight world champion Manny Pacquiao. The American, who hasn't fought since being knocked out by Liam Smith last April, recently gave a scathing take of KSI's boxing skills and shared his concern on Twitter about the YouTuber potentially getting "really hurt" in a fight.
KSI replied to the video by commenting a crying with laughter emoji, to which Vargas replied: “I wish you much success bro. Just giving my humble opinion.” KSI gave somewhat of a hostile response to the former world champion by saying back: “Can have all the opinions you want my g.”
