Chad Mendes has been understandably talking a lot about Jose Aldo as UFC 179 approaches, but more recently, the featherweight contender has been forced to discuss Conor McGregor.

Of course, the latter has put himself right smack dab in the middle of Mendes’ radar, by making fun of his height and dismissing his skills. The two recently appeared on BT Sports’ “Beyond the Octagon” show, and it didn’t take long for the trash talk to fly.

You can watch the heated exchange below.

Mendes will face the champion Aldo at UFC 179 on Saturday night, which will take place in Rio de Janeiro, Brazil.

The two fought in January, 2012, and Aldo scored a first round, knockout win.
