Watch Johnny Nelson go through the tactics as Anthony Joshua and Carlos Takam prepare to go toe to toe on Saturday, live on Sky Sports Box Office.
Nelson believes Joshua, the IBF and WBA 'super' heavyweight champion, has got so much going for him against his late-notice opponent in Cardiff and he just needs to play to his strengths.
"We know he can fight, we know he can punch, he's got the speed and accuracy, we know he can take a shot," Nelson said.
"But now again his defence was a little loose against [Wladimir] Klitschko back in April, when he was hit flush by a right hand on the temple and went down. He got up and fought like a fighter has to fight but he's got to keep that left hand up because that's the shot that Klitschko was catching him with from the beginning and all the way through.
"Takam has to get in close, get to his chest, throw that right hand that he's got to land on the temple of AJ because he's showed that he keeps that left hand low, too low at times.
"He's got to keep him off, keep him long, don't let him get in close, bring the shots up.
"Takam has to pressure him, push him back, make him fight off the back foot and throw the shots in. That's going to be the hardest job for Takam because of the height and reach of AJ and his strength and speed."
