Maybe it was just a way to spark some social media buzz, but Conor McGregor  issued a challenge Saturday night.
Moments after a bout between Diego Sanchez and Michel Pereira ended via disqualification, McGregor posted on Twitter.
Conor McGregor Vs Diego Sanchez
— Conor McGregor (@TheNotoriousMMA) February 16, 2020 
Sanchez was declared the winner due to an illegal knee landed by Pereira. The bout was the co-main event for UFC Fight Night 167 .
McGregor, of course, is coming off a win over Donald Cerrone. Maybe this is the former UFC champion starting a course to dispose of the “legends” of the sport.
