Welterweight contender Julio Diaz says Amir Khan is still making the same mistakes that caused him to lose recent fights to Lamont Peterson and Danny Garcia. Khan admits that he will have to spend more time with his trainer Virgil Hunter in San Francisco after being floored on his way to a twelve-round points victory over Diaz at the Motorpoint Arena in Sheffield on Saturday.

The Briton quickly bounced up off the canvas in the fourth round, but after a count there were more worrying moments before he looked on the verge of being stopped in the eleventh round. Khan won with scores of 114-113, 115-113 and 115-112.

Diaz, 33, has no intention of retiring and hopes to face another light-welterweight contender, insisting Khan never hurt him.

"I couldn't finish him because he became more dangerous when he was hurt," Diaz said. "I focused too much on the knockout and let the rounds slip away. It was a fair decision.

"He still made the same mistakes. You can't change a fighter overnight, you have to be there 24/7 [in training camp in San Francisco]. He needs to stop exposing himself."
