Top UFC lightweight Islam Makhachev responded to criticism from former interim champion Justin Gaethje. The American previously said the Russian fighter is undeservedly ranked fifth in the lightweight division.
"Hey Justin, are you upset that I'm getting closer to you in the rankings?", Makhachev tweeted.
Makhachev, 30, will fight Dan Hooker on October 30 at UFC 267 in Abu Dhabi.
