Rafael dos Anjos and Conor McGregor were supposed to fight at UFC 196, but an injury to the Brazilian halted those plans.
It was set to be a massive fight as McGregor, the featherweight champion at the time, was moving up to lightweight to try and become the first ever simultaneous two-weight champion in the UFC.
Dos Anjos then lost this belt to Eddie Alvarez, and Alvarez got the fight with McGregor instead. So, with McGregor looking to return to the Octagon in January, the Brazilian has called for the fight to finally happen.
