Amir Khan is promising an impressive response as he returns as a smarter and more serious fighter in his first bout since being knocked cold by Saul 'Canelo' Alvarez.

The English welterweight has not boxed since stepping up two weight divisions to face Mexican Alvarez almost two years ago, but Khan (31-4, 19 KOs) insists he feels in better shape than ever ahead of Saturday's non-title bout against Canada's Phil Lo Greco (28-3, 15 KOs) in Liverpool.

"I'm training as hard as ever and I feel physically better than I did when I was 28," Khan said.

"In training I feel better than ever and the way sparring has gone I'm a little bit more wary, I'm a bit smarter now, I'm letting my skills win me rounds in sparring.

"I'm letting my skills from now on win me fights.

"Me having that knockout against Canelo made me a serious fighter, a fighter who wants to make things better and finish on a high."

Canelo stopped Khan in the sixth round for the Bolton boxer's fourth professional defeat after also losing by knockout to Breidis Prescott in 2008 and Danny Garcia in 2012. Khan was also outpointed by Lamont Peterson in 2011.

But Khan, who last held a world title six years ago, dismisses the suggestion the knockouts have taken their toll on him ahead of his first fight in England for five years.

"I'm 31, at the peak of my career and I don't think those knockouts are going to be really bad," Khan said.

"I jumped back from being knocked out by Prescott to win a world title, I jumped back with good performances against Luis Collazo and Devon Alexander after getting beaten by Garcia, so I have had my best performances after getting beaten.

"I go back to the drawing board and work on my skills and become a better fighter. I'd rather get knocked out by one punch by Canelo than take numerous punches. The shots I've taken when I've been knocked out, there haven't been that many really.

"At the moment my body feels great, I've only had that one hand operation in the whole of my career. Other than that, I've had no other worries, I've always been fit and strong."
