Anthony Joshua has vowed to concentrate on his own game ahead of his heavyweight meeting with Kevin Johnson at the O2 Arena on Saturday.

Having dispatched Raphael Zumbano Love last time out, Joshua, 25, is expecting a tougher test against 'Kingpin' Johnson, who is a former heavyweight challenger and went the distance with Vitali Klitschko in 2009.

However, Joshua, who has an unblemished record after 12 fights so far, refused to get drawn into a verbal war with the 35-year-old, telling Sky Sports News HQ: "Kevin Johnson is very experienced and very defensive.

"I want do a job on him for sure but I am not going to get carried away.

"I am going to break him down bit by bit."
