Although DeGale looked to be in control for most of the fight Khatchikan had his moments and proved more than capable of holding his own against the WBC silver super middleweight champion.
DeGale finally got the job done after 2.58 of the 11th round when a sustained combination of punches to the body forced the stoppage after Khatchikan dropped to the canvas,twice.
DeGale, who was cut above the left eye in the second round, spoke to Channel 5 sport after the fight, saying: "I knew I was wearing him down. I knew the first couple of rounds would be difficult. He wanted to fight, but I broke him down. The better the opponent, the better I box.’’
Regarding some scary moments in the fight where he looked in trouble DeGale added: "Because it’s so easy, I switch off. It’s stupid. I could see at the press conference that he really wanted it. I’ve done eleven rounds, ended up stopping him... I’m pleased.
"It’s about moving on now and just getting that world title. That’s what it’s all about.’’
DeGale had planned to fight Badou Jack in May in a final eliminator for the WBC super-middleweight title but Jack lost in the first round to Dereck Edwards on Friday night.
