US boxing promoter Don King likened British star Amir Khan to the great Sugar Ray Robinson after watching the 18-year-old win his second pro bout.
Khan dominated a four-round contest over Baz Carey in Cardiff, drawing wild praise from the influential King.
"I was very impressed with Amir - he was super-sensational," said King.
"He has blinding hand speed and great dexterity. He can punch going forwards and backwards. Robinson, the greatest boxer who ever lived, did that."
Robinson dominated the welterweight and middleweight divisions in the 1940s and 1950s.
And, after watching Saturday's bout from ringside with Khan's promoter Frank Warren, King said he expected the teenager to challenge for titles soon.
"I think he can almost go to the top with some of the best guys right now, but he's not quite there physically," said the American.
"When he gets the stamina and bigger, he will be ready to do it. Boxing needs someone like this young man."
"There's no one like him in the world today."
Khan was typically modest in victory.
"I would give myself eight or nine out of 10 but there is a lot more I can do and I will go back to the gym and work on things," said the Bolton fighter.
"In an eight-round fight you would have seen a lot more. But I have gone four rounds now and Carey made me work because he was tough."
