Ultimate Fighting Championship (UFC) lightweight champion Conor “Notorious” McGregor is gearing up for what may become the payday of his career. “Notorious” is set to face off against boxing phenom Floyd Mayweather Jr. inside a boxing ring on Aug. 26 inside the T-Mobile Arena in Las Vegas, Nevada.

For motivation in his training, the UFC lightweight champion has decided to make a change in the gym from which he trains. A mural of the champion punching Floyd Mayweather Jr. in the face can now be seen prominently on one of the gym’s walls.

In the video below, Conor McGregor can be seen reacting to the mural for the first time.
