 Khan's first-round stoppage of Medjadi was his quickest so far |
Amir Khan believes his first-round knockout of Mohammed Medjadi at Wembley on Saturday is proof he is close to becoming a complete fighter. Khan, 20, connected with a stunning overhand right to finish the action after just 55 seconds.
He said: "Every fight I'm learning. I've shown speed, stamina and now I've shown the power's there as well.
"I just have to build the experience. In another four or five fights, I'll be ready for the big boys."
Khan's only disappointment was that he did not have more time to put his training into practice in a competitive situation.
"He had six weeks to train for the fight, so while it was frustrating, it shows I'm going the right way," said Khan.
"I always train for eight rounds and the training I did for this fight was hard so when I knock someone out in the first round, that hurts me.

"But why risk it? If you know you can knock someone out in the first round, finish the business."
Khan added that his immediate future lies in the lightweight division, despite suggestions he is a natural light welter.
"My weight is lightweight. I feel sharp, I feel strong and my reactions are a lot quicker," said the Bolton native.
"I've weighed in before at 9st 13lb and I've been a little bit sluggish. I reckon I could even make super feather."
Meanwhile, promoter Frank Warren said he will continue to bring Khan along at a steady pace and that a world title shot is still a couple of years away.

"Amir's not going to fight for a world title this year, so everyone can get that out of their heads," said Warren.
"He's 21 in December, we'll see how he goes for a year after that and then it will be great to fight for a world title.
"He's only had 11 fights, but by the time he's had 20 he'll be ready.
"Amir needs protecting from himself, he'd fight for a world title tomorrow but it's got to be done at the right time.
"It's easy to make world title fights. But there have been so many fighters who have screwed up their careers because they were on an ego trip and weren't ready for it."
