AMIR Khan says topping the bill in Las Vegas this month is a dream come true.

The Bolton superstar takes on Devon Alexander on December 13 as the headline act at the MGM Grand in America's fight capital.

And the 27-year-old is vowing to make it a night to remember with a win against his American opponent likely to take him a step nearer to realising another dream – to take on Floyd Mayweather Jnr.

It is not the first time Khan has fought in Las Vegas – his most recent fight in May seeing him beat Luis Collazo with a unanimous points verdict on the undercard of Mayweather v Marcos Maidana.

This will be Khan's fifth Vegas date in four years – his debut coming in December 2010 when he beat Maidana.

Khan said: "To top the bill at a venue like the MGM Grand is amazing.

"It is arguably the most well-known arena in the world for boxing.

"It is an honour to go and fight as the main event there and a dream come true for me.

"It will make me work even harder to go in there and succeed."

The countdown to Khan's ring return is gathering pace but Bolton's 2004 Olympic silver medalist says he is ready to roll after a positive training camp under the watchful eye of Virgil Hunter.

It will be his fourth fight since he ditched Freddie Roach in 2012.

Khan added: "The training camp has gone really well and I could step in the ring next week if necessary.

"We have covered all bases in training.

"My conditioning coach, Tony Brady, and trainer, Virgil Hunter, have been brilliant in helping me progress towards being a better fighter.

"The 147 weight suits me a lot more like I have said in the past.

"I feel so much stronger physically."

Alexander is undoubtedly a tricky opponent for Khan with just two defeats in 28 professional bouts.

But he believes he is ready to deal with the pressure and hopes to end his year on a high.

He said: "There is pressure in every fight.

"It is two guys who are quick and skilful and both at their peak.

"We are two young lions hungry to get to the top.

"It has been six months since I last fought but I have been active during that time and spent a lot of it in the gym as well.

"I'm ready for him and determined to show I'm the better fighter.

"It could end a great year for me and 2015 could be even better against some big names."
