Khan described the fight as the stiffest of his career to date

The 19-year-old, who outpointed Laszlo Komjathi in his seventh professional bout on Saturday, said: "I would love to show them what I've got."

His promoter Frank Warren has not ruled out a trip to the States but insists Khan is not ready for a title fight.

"Everyone asks when he will fight for a title but he's got to learn his trade," Warren told BBC Sport. "I know how to make Amir's career a success."

Khan showed supreme confidence as he notched up a six-round points victory over his Hungarian opponent in Belfast.

But Warren said he is still exercising caution as he plots the Bolton fighter's career.

Just imagine what I will be like after seven more fights Amir Khan

"He is on a leash and wants to be let off but he is nowhere near ready for that yet," he said.

"He's got a lot to learn. But Amir hurt Komjathi a couple of times, and if it had gone longer he would have stopped him.

"He's in that situation where, if he stops somebody they're nobodies, if he goes the distance, they can't punch.

"It's ridiculous people asking, 'why is Amir not fighting for a world title now?' Everybody's got to back off and let him learn his trade.

"I don't think I've hyped him - it's just got a life of its own. You've not heard me saying he's going to win the world title next week.

"I'm the one who's saying, 'let's temper this a little, let's be rational and let's not ruin a great talent'. I won't allow it to happen."

Khan acknowledged his latest test, which saw him win by a 60-55 verdict, was a step in the right direction.

The Bolton boxer said: "I learned more in that fight than I have in my last four put together.

"I needed someone who was going to come forward and not let me bully him and that's what he did.
