As for Joshua, the super-heavyweight Olympic gold medallist of 2012 insists he is grounded after winning his first world heavyweight title with a 16th straight career stoppage.
“I ain’t gonna get too carried away,” he said. “Every fight gets better and better.
“It’s not just about power. It’s about speed and precision.
“[Martin] was big and brave enough to bring his title to the UK. Respect to him.”
Joshua could now book a unifying title date with Tyson Fury if the latter beats Wladimir Klitschko in Manchester this July.
David Haye, fresh out of retirement, is also an option for 26-year-old Joshua.
