Fabricio Werdum thinks the UFC will soon have a new undisputed heavyweight champion. Werdum, a former UFC heavyweight champ himself, believes Ciryl Gane will defeat Francis Ngannou in their championship bout on Jan. 22 in their UFC 270 headliner. Gane currently holds the interim title, which he won in August by stopping Derrick Lewis . Meanwhile, Ngannou is set to make his first title defense as he looks to compete for the first time since knocking out then-champion Stipe Miocic in March.
