Michael Bisping Its not perfect circumstances but this is my lifestyle, he told Sky Sports in an exclusive interview. Its short-notice, so bittersweet, but Ive worked a lifetime for this.I need to put him away because five rounds favour him, lets be realistic about that.

Michael Bisping (left) aims a left hook at Luke Rockhold in 2014 Hell look to drag this into a five-round war where hes got the advantage, thats a fact. Ive got to take him out early so Ill go back to my younger days - live by the sword, die by the sword.Ive got two-and-a-half weeks - my weight isnt too bad so Ill have to go on an extreme diet, but I wouldnt have it any other way. Two-and-a-half weeks of intense, crazy work.I actually texted [UFC president] Dana White on Tuesday saying, If someone is hurt, Ill take it. I pitched my case. The first time I heard was the UFC announcement. Michael Bisping (left) evades a punch from Luke Rockhold Bisping has already met Rockhold and came off worse, dropping to a submission defeat in 2014 amid heated personal animosity.The rivalry was sparked by Bispings insistence that he had triumphed in a behind-closed-doors sparring session and that fateful tale still instills belief.Ive fought this guy before in the gym then we fought for real, its 1-1, the 37-year-old said. Michael Bisping appeals to the referee after being cut above the eye by Luke Rockhold He never hurt me with anything. He head-butted me in the first round which opened a nasty cut. Up until that point it was going very smoothly. Congratulations to him for getting the job done but there were mitigating circumstances.Nobody was in there except for me and him - I know how he felt, and the strength of his kicks and punches. Those things make me comfortable in taking this next fight.Bispings most recent outing was a career-best win against former middleweight champion Anderson Silva at Londons O2 Arena, with Rockhold watching from ringside. Rockhold can be as smug as he likes but when I dropped him in sparring, he certainly felt it. Michael Bisping Prior to that fight Rockhold told Sky Sports that if we fought again I wouldnt need to keep my hands up which drew laughter from Bisping.The Brit replied: Im pretty sure Anderson said the same thing but he got dropped twice and out-boxed consistently. Rockhold can be as smug as he likes but when I dropped him in sparring, he certainly felt it. Well see how smug he is after the fight.This isnt a case of cashing in and trying to earn a few quid before calling it quits. I just beat the greatest of all time, Silva, and Im the only person to legitimately beat him.This is my destiny, I love the way its come together.
