In just 76 seconds, Amir Khan was able to defeat Dmitriy Salita on 5th of December for his first defence of the WBA light-welterweight title in Newcastle.
Khan threw a lightning fast left-right combination which floored Salita after just 10 seconds, leaving him unable to recover.
The referee stepped in after Khan continued his assault on Salita, after the New Yorker attempted to recover by getting to his feet. However, he remained off balance which forced the referee to step in.
Khan is only 22 and currently has 22 wins and 16 knockouts in his career of 23 professional fights.
Khan will be helping Manny Pacquiao get ready for his fight against Floyd Mayweather at the Wild Card gym in Los Angeles.
"It was very explosive. The fight was just what we asked for, what Freddie asked me to do. We had too much power for this guy," a delighted Khan told reporters after the fight.
"I'm a growing young man and developing as a man. Freddie said to take it easy, pick the right shots and you'll take this guy out and we did.
"Freddie is a great trainer, he's like a father figure to me and to have him in my corner means a lot. Everyone knows I'm a hard-working fighter and if you put the hard work in you're going to get the benefits.
"After the first shot I could see his legs buckling and I just had to take my time. I knew he was going."
Roach said: "I would give him an A+.
"I said if you hurt him, finish him. We've been working on that power and the fight was really over after that first punch."
