British heavyweight Anthony Joshua believes that exploiting Kevin Johnson's weaknesses will lead to him becoming the first man to stop the American inside the distance.
Joshua's 11th professional fight will come against a man who has taken the likes of Vitali Klitschko, Tyson Fury and Dereck Chisora the full 12 rounds, but the 2012 Olympic gold medallist is confident of overcoming someone whom he describes as his "toughest challenge" to date.
The 25-year-old told Sky Sports News: "Most definitely, Kevin Johnson will be my toughest challenge, physically and verbally.
"I haven't gone in with the mindframe of 'I need to knock him out within one, two or three rounds'. Sometimes it's subconscious when they show a chink in their armour you exploit them and I'm sure Kevin Johnson will show weakness.
"With the training I'm doing over Christmas and in January, I'll be able to exploit weaknesses in Kevin Johnson."
If Joshua can defeat Johnson and come through his next scheduled contest in Newcastle in April, the Londoner could challenge for the British title during the summer.
