Conor McGregor may be training hard for his upcoming fight against Floyd Mayweather, but it takes years to perfect some of boxing’s simplest techniques.

Here, we get a breakdown of three basic skills the UFC star may just not understand while facing one of the sport’s greatest of all-time.

In the clip, we see throwback footage of Mayweather demonstrating skills like “Fighting in the Pocket”, “Fighting Toe to Toe” and footwork and rhythm patterns. We also see him using these techniques in some of his biggest fights.

Will McGregor recognize these skills while fighting Mayweather? We’ll see August 26th.
