Khan vs Collazo: Amir Khan believes extended gym time will yield better results against Collazo

Amir Khan returns to action after a year of inactivity this Saturday night, facing Luis Collazo on the date he originally expected to be going head-to-head with boxing's current king, Floyd Mayweather.

The 27-year-old Khan (28-3, 19 KO) says he quickly got over losing out in the Mayweather sweepstakes, and is now fully focused on Collazo (35-5, 18 KO), saying he wants to impress on Saturday.

"It was a difficult time," said Khan. "But the fact is I moved on fairly quick when I knew the Mayweather shot wasn't happening. 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.

"I wanted a tough challenge at welterweight and not just to go in there against some average guy. Collazo is a legitimate welterweight who is very confident after his win against Victor Ortiz but I know I have the tools to beat him," said Khan.

Khan believes that an extended period working in the gym with trainer Virgil Hunter will yield better results.

"You're going to see an improved Amir Khan, the best Amir Khan, there's no doubt in my mind about that," he said.

"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.

"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 3rd 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," said Khan.
