Ruslan Magomedov believes Conor McGregor’s trash-talking tactics is a form of “psychological warfare.”
If you asked the current crop of Russian fighters, they'd inform you that trash talking was not a particularly popular tactic for fighters to apply ahead of a clash. It was looked down upon by fighters, and frowned upon by society in general. Recently, however, combatants like Conor McGregor and Khabib Nurmagomedov shifted opinions on trash talk slightly, at least for MMA fans.
According to Ruslan Magomedov, McGregor is particularly popular in Russia because he actually followed through on his predictions and bizarre claims.
