The coach of former Ultimate Fighting Championship champion Charles Oliveira has made public his secret weapon to prepare Oliveira for his next fight.
In October, ex-lightweight king Oliveira will vie for the vacant belt against Islam Makhachev at UFC 280. The Brazilian only lost his title after missing weight by a fraction of a pound, and he went on to tap Justin Gaethje in the first round to record the victory. The surging 32-year-old has beaten Kevin Lee, Tony Ferguson, Michael Chandler, Dustin Poirier and Gaethje in the span of a little over two years, firmly cementing himself as the best fighter in the division.
