Amir Khan has claimed that he already feels stronger at 147lbs ahead of his first bout of 2014.
The British fighter was left disappointed when a proposed meeting with Floyd Mayweather Jnr failed to materialise, but he is confident of impressing at a higher weight.
"I've already moved up to 147lbs," Khan told reporters.
"I think now being at 147lbs it's only going to make me stronger, more healthier and happier when I go into a fight.
"The speed's gonna be there, the power, and the hunger as well. I won't be tired or weak, so I'm excited. The future holds a lot of things for me."
