LAS VEGAS (Nevada) (AFP) - Britains Amir Khan is confident and motivated for his debut in Las Vegas , next weeks World Boxing Association super lightweight title defense against Argentinas Marcos Maidana. When I win this fight convincingly, people will realize how good Amir Khan is, Khan said in a teleconference Thursday to promote the December 11 bout. It has been a great training camp. I am in one of the best shapes of my life. Khan, 23-1 with 17 knockouts, or mandatory challenger Maidana, 29-1 with 27 knockouts, will face Januarys winner between US unbeatens Tim Bradley and Devon Alexander, the World Boxing Council champion, in a 2011 unification bout.But for now, Khan is focused upon taking a sixth triumph since suffering his only loss, that coming in a 2008 knockout loss at the hands of another South American, Colombias Breidis Prescott. That defeat helped me get this far in my career. That defeat gave me a wake-up call, Khan said. Im training different. My focus is different. I listen to my trainer and train a lot harder. It was a blessing in disguise. It also keeps Khan from making boastful knockout predictions. We dont want to go in looking to knock somebody out. We want to stick to the game plan, Khan said. There will come times we want to put pressure on and times we want him to come forward. If Im ready for the best Maidana I will be ready for anything. Khan, who turns 24 on Wednesday, has matured under trainer Freddie Roach even though it has meant spending significant time away from his home in England. He sets things up now. He doesnt go in looking for one-punch knockouts, Roach said. He knows how to break a person down. He knows how to work his jab. Ive never had a fighter listen so well and take to the game plan so much. We havent lost one round since we have been together. I dont see us losing a round here either. That doesnt mean Roach or Khan are taking Maidana lightly, especially not after he has retired 22 of 27 foes in three rounds or less. He does have KO power. We respect that. Were ready for what he has, Roach said. Hes a very good fighter. We will break him down and I think he will knock (Maidana) out in the later rounds. Khan comes in off a victory over Paulie Malignaggi in New York last May in his US debut, one that boosted attention and income for this fight. This fight is a lot bigger than it would have been six months ago, Khan said. Were both getting a lot more than we were offered the first time. We have people on the edge of their seats.Maidana, 27, has won four times since a split decision loss last year to Andre Kotelnik in his first world title fight. Khan beat Kotelnik five months later to take the title. This fight is very important. Im hungry to get the title, Maidana said. The South American fighter said he is ready for whatever style Khan might choose to present. Im ready for anything, Maidana said. If he wants to stay with me thats my fight. If he wants to move around, Ive learned how to cut the ring and beat him at the ropes and force my fight.
