British heavyweight Anthony Joshua has insisted that he is fully focused on his fight with Rafael Zumbano Love in Birmingham on Saturday night.

Joshua is pencilled in to face American Kevin Johnson on May 30, but as he continues his comeback from a stress fracture in his back, the 2012 Olympic gold medallist has revealed that he is only thinking about delivering an "explosive" display against the Brazilian.

The 25-year-old told Sky Sports News: "Saturday is very important. My conditioning is improving day by day and my focus is totally on this fight. I want to put in an explosive performance for the fans."

Joshua has won each of his 11 professional fights inside three rounds, while Love has won 36 times in 47 appearances.
