Anthony Joshua’s reaction the moment he knocked out Charles Martin is brilliant

In the end, it all seemed so easy.

Anthony Joshua made light work of Charles Martin to become the new IBF heavyweight champion of the world, ruthlessly dispatching his opponent in the second round at The O2. Having already knocked the American to the canvas once in the second round, Joshua smelled blood and quickly floored him again with a straight right. With most lenses trained on the 29-year-old southpaw as he was felled for the second time, one camera angle captures Joshua's reaction to his contest-ending punch. A grinning Joshua shrugs his shoulders as he strolls away from Martin, appearing almost apologetic for ending the fight with such ease. Cool as f**k.
