Haroon Khan is convinced he can emulate his famous brother Amir and claim his own world titles.
The 21-year-old younger Khan, after 66 wins as an amateur, makes his professional debut on his brother's undercard in Sheffield on Saturday.
He will take on Bulgarian Stefan Slavchev in a four-round super-flyweight contest at the Motorpoint Arena.
Haroon Khan said: "I'm looking forward to it. I have been waiting for this day for a long time and now it has come.
"I can't wait to get in the ring and show my talent.
"I am a bit nervous but it is going to be a big night and I have trained so hard for this fight.
"I am not going to be a loser. I have sacrificed so much and I am not going to let the training camp go to waste.
"Whoever was to come in front of me, I am sure I would be too powerful for them.
"I know I am going to get comparisons with Amir but even if I achieve half of what he has achieved, I will be happy with that.
"But I know I am capable of becoming a world champion."
Haroon Khan has followed Amir throughout his career and his elder brother intends to return the favour.
Amir this weekend has his own concerns as he takes on Julio Diaz in the main event in Sheffield but hopes to guide Haroon as much as he can.
Amir Khan said: "It is going to be brilliant with him fighting on the same card as me.
"I thought this time would never come, but it has.
"It is a great move he has made to turn professional. There are a lot of big fights out there for him.
"As long as he is disciplined and trains hard I am sure he can go all the way.
"I want to advise him from day one, all the way to the top. As long as he listens I am sure he can go all the way."
