Simply knocking them down, it appears, is no longer good enough for the affable world heavyweight champion and that might spell bad news for Carlos Takam, who has stepped in for the injured Kubrat Pulev at 12 days' notice. Joshua is methodical in assessing his opponents' body types and skill-sets so swapping Pulev for Takam, he believes, is an opportunity to demonstrate part of his own arsenal that has so far been restricted to unfortunate sparring partners.
