"No I still wouldn't call [St-Pierre] pound-for-pound best in the world, but I'd say he's number two, " White said Saturday after the fights.
St-Pierre (18-2) and Silva (23-4) are the two UFC fighters most debated in pound-for-pound rankings discussions.
Outside of a disqualification loss due to an illegal kick, Silva has been undefeated for almost four years. At UFC 97 on April 18, Silva will look to set the record for the most consecutive UFC wins with nine.
"Anderson has been annihilating everybody for a long time," White said. "Georges has some work to do now. [If] Georges takes out Thiago Alves, he's on his way."
St-Pierre's next title defense at a date to be determined will be against the American Top Team fighter Alves, who earned his number one contender status with victories over Matt Hughes and Josh Koscheck.
