Old dog Vladimir Matyushenko will take on new trick Alexander Gustafsson at the upcoming UFC 141: "Lesnar vs. Overeem" pay-per-view (PPV) event this Friday night (Dec. 30, 2011) in Las Vegas, Nevada.

Matyushenko (26-5) is still trucking along at the ripe old age of 40 and outside of a shellacking he took at the hands of division champion Jon Jones, has been quite the force since his return to the Octagon.

"The Janitor" most recently mopped the Toronto floor with Jason Brilz's lifeless body back on April 30 at UFC 129, winning via knockout in twenty seconds flat and improving to 4-1 as a Zuffa employee.

Is this tough-as-nails veteran going to spoil the rise of one of the division's brightest prospects? Or will "The Mauler" live up to his nickname by finishing the wily Belarusian and moving one step closer to putting himself "in the mix?" How do you see this 205-pound scrap unfolding?
