Conor McGregor’s camp dropped a new video Thursday afternoon (June 29), in response to the clip Floyd Mayweather posted earlier in the day that shows him going HAM on a double-end bag in the gym.

In McGregor’s video, the Irishman can be seen working the bag and delivering punches with real power on them.

It’s no secret that Mayweather can box circles around almost any fighter, but Conor could catch him with a shot and do some serious damage, based on the way he was attacking that heavy bag. Just ask Andre Berto.

Mayweather might be 40 and coming out of retirement, but he looks FAST!

Check out his video below that prompted McGregor to drop his own training video:
