The world will see the best of me - Khan
Amir Khan says the world will see how much he has improved during his time out of the ring when he faces Luis Collazo on May 3.
The Briton has not been in action since defeating Julio Díaz in April 2013 in Sheffield, but is confident of conveying to everyone how hard he has worked on becoming a better competitor when he returns on Saturday in Las Vegas.
"You're going to see an improved Amir Khan, the best Amir Khan, there's no doubt in my mind about that," Khan said.
Khan, set to make his debut at welterweight, has been working with American trainer Virgil Hunter in San Francisco and believes that will give him the edge over Collazo.
"Over the last 12 months I've been in camps with Virgil and we've been working on certain aspects of my game that I never really got the chance to work on because I just didn't get the time as I was fighting so often," he said.
"Through the last few months I've been focusing on improving myself and adding certain things to my game. Because I didn't have an opponent lined up and I wasn't fighting I had the time to look at myself and work on things I wanted to work on.
"On May 3 I'm going to put that all into practice on the biggest stage and not only beat Collazo but look to beat him in real style."
A fight against Mayweather Jr failed to materialise, but Khan, who will be competing on the undercard of the American's bout against Marcos Maidana in Las Vegas, admitted being overlooked by Mayweather Jr was "a difficult time".
"The fact is I moved on fairly quick when I knew the Mayweather shot wasn't happening," he said.
"It was just about refocusing my mind on the next opponent and luckily we were able to announce Luis Collazo straight away which allowed me the chance to get back in the ring as soon as possible."
