The Bolton fighter turned 28 this week and believes that defending his WBC silver welterweight title in style will ensure next year brings even bigger fights against the likes of Floyd Mayweather Jnr and Manny Pacquiao.
Khan said: “My dream was to turn professional one day and fight at the biggest arenas at the world and have my name up in lights. This is where I’m at.
“It took 10 years to get here but it’s a dream come true. I’m topping the bill here. I’m the main attraction in Vegas. It took a lot of fighting, a lot of training and a lot of sacrifices to get into this position.
“My goals are to fight the biggest names in boxing. After Alexander, there are names like Mayweather and Pacquiao getting thrown at me. It’s all about fighting at that elite level of boxing.
“Roll on 2015. It’s a big year for me. Hopefully I’ll get past this fight, finish this year off with a big bang and go on to a huge year for me in 2015. There are going to be some huge fights for me.”
Since back-to-back defeats to Lamont Peterson and Danny Garcia in 2011 and 2012, Khan has strung together a hat-trick of victories against Carlos Molina, Julio Diaz and Luis Collazo.
