In true form, Ultimate Fighting Championship (UFC) will close out another successful year with one of the biggest and most anticipated main events taking place this Friday night (Dec. 30, 2011) at the MGM Grand Garden Arena in Las Vegas, Nevada.

It literally doesn't get any bigger than former UFC heavyweight champion Brock Lesnar welcoming former Strikeforce and DREAM heavyweight champion, and K-1 Grand Prix champion, Alistair Overeem, to the promotion at UFC 141: "Lesnar vs. Overeem."

Overeem, who will make his much anticipated Octagon debut in "Sin City," has been documenting his journey to the UFC in his personal blog via Yahoo!Sports, detailing his trials and tribulations leading up to the blockbuster year-end pay-per-view (PPV) event with the world's largest mixed martial arts (MMA) promotion.

In his latest (and perhaps final) blog entry before fight night, "The Demoliton Man" talks about the confidence he has in his striking, the respect he has for Lesnar's punching power, and his prediction for what will happen when the two behemoths collide in the center of the eight-walled cage.

Check it out:

"While he doesn't have world-class technique, Mr. Lesnar is a big man who can punch, and I have trained to avoid Lesnar's strikes like I would any opponent. This fight is scheduled for five rounds, and I have trained for five, but I personally think I will win in the first round. I will knock Brock Lesnar out. Second round at the latest. I never underestimate anyone, and Mr. Lesnar is a former UFC world champion, but this is it, the chance to send a message to my fans, my critics and to UFC fans who maybe haven't seen too much of me yet. All the talk, all the would-be distractions, all the training and the hours in the gym and on the mat - it all comes down to Friday night. I'm an all-around fighter. I do everything. I've got wrestling, I've got submissions and I've got striking. Of course, I like to knock people out -- and that is the plan Friday -- and my striking is something that I focused on because I wanted to be the first MMA champion to also win the K-1 kickboxing Grand Prix, which I did a year ago. Obviously my strikes were my best weapons even before K-1, but they got a lot better because of the K-1 competition. Right now, I don't feel anyone in the division can strike with me, but this is MMA and I have prepared very hard for any eventuality. He wants it, I want it. One shall stand, one shall fall."

Overeem's journey to the UFC has been quite a tumultuous one to say the least.

From relocating his training camp from Las Vegas to Holland to care for his ailing mother, to his Nevada State Athletic Commission (NSAC) drug test fiasco, the hulking Dutchman has dealt with all obstacles rather calmly, insisting all along the way that nothing has been a distraction and is ready to answer his critics wrong this Friday night.

The time for talking is slowly coming to an end.

In just less than three days, Overeem and Lesnar -- two of the biggest heavyweights to ever step foot inside the UFC's world famous Octagon -- will collide in a number one contenders match for the right to face newly crowned division champion, Junior dos Santos.

As Overeem so eloquently puts it, "one shall stand, one shall fall." When it's all said and done and the dust settles, who, in your opinion, will rise as the new challenger for the coveted UFC heavyweight title?
