Lou DiBella, who promotes top welterweight Andre Berto, believes Amir Khan should seriously consider staying at 140-pounds.  DiBella watched Khan's recent split decision loss to Lamont Peterson and wasn't impressed with the British star's inability to bully Peterson, who most viewed as the smaller man. DiBella scored the fight for Peterson and felt the referee, Joe Cooper, was justified in docking the British star two points for pushing.

"Personally I scored Lamont Peterson winning narrowly but that's not the issue. There's no real controversy about the referee and the judges. You can't go shoving opponents across the ring with both hands. Amir got warned and got docked. End of story," DiBella told Jeff Powell of Daily Mail.

"But I am a huge admirer of his wonderful natural ability and there's something wrong In his head, in his thinking. I don't question his courage for one minute but I couldn't believe how he let himself be backed up by a smaller man who is a light puncher. He should have dominated this fight and had he done so he would be heading for a  super fight instead of going back to regroup.

'With his speed and skills Amir should have been the one going forward. Instead he went backwards and took punches he had no need to take. On this evidence, even if he hadn't blow his chance of fighting Floyd Mayweather he should still be thinking seriously about whether he should go up to welterweight. If he can't put away 140-pounders how's he going to stop a Mayweather?'
