Conor McGregor has named Nate Diaz as his toughest challenger in the UFC during a Q&A with fans.
McGregor, 34, is gearing up for his UFC return having not fought since breaking his leg against Dustin Poirier in their trilogy fight last July. The former two-weight champion, who has fought a who's who of names during his UFC run, insists Diaz has been his toughest challenger to date despite having been stopped by the likes of Poirier and bitter rival Khabib Nurmagomedov.
Diaz and his brother Nick are best known for their relentless pressure and outstanding cardio, with both of these assets being on show when McGregor fought Diaz on short-notice in March 2016. The pair met in a welterweight fight after McGregor's original opponent Rafael Dos Anjos withdrew, as Diaz absorbed an early onslaught from McGregor in the opening round to tap him out with a rear-naked choke.
