So much has changed since then.”I was the interim featherweight world champion at the time and Donald predicted I wouldn’t get through [Jose] Aldo. I got through Aldo.

Obviously you’ve seen him compete so many times it’s hard not to respect Donald right now at this stage and he has my respect.”Although there will be blood spilled on Jan. 18, it will not be bad blood, and for the Mystic Mac prediction, it will be a KO.”Saturday night. #UFC246 pic.twitter.com/Tu6dgW6TTq— UFC (@ufc) January 16, 2020Cerrone is excited about facing McGregor and said it would be the biggest challenge of his career so far.
