#2. St-Pierre vs. Khabib Nurmagomedov

GSP felt a fight against the undefeated Khabib would have done more for his legacy and been worth the risk. At one point, he was even open to cutting down to 155lbs to challenge ‘The Eagle’ for his UFC lightweight championship. St-Pierre could have done something no other fighter has done in UFC history by winning a championship in three weight classes.
When the fight didn’t materialize, ‘Rush’ decided to officially announce his retirement from MMA. In 2021, White tried to convincing Khabib to continue fighting and rumors of 'The Eagle' vs. 'Rush' began to swirl again. Ultimately, the thought of St-Pierre and Khabib fighting at either 155lbs or catchweight was intriguing, but unfortunately not meant to be.
#1. St-Pierre vs. Anderson Silva
Georges St-Pierre and Anderson Silva, two of the greatest fighters of all time, had multiple opportunities to prove who was the best, but a fight never happened.
For years, GSP dominated the welterweight division, while ‘The Spider’ dominated the middleweight division. St-Pierre vs. Silva would've most likely taken place in a stadium and could have set records for the promotion.
In 2010, it looked like the UFC were looking to make the superfight a reality. In the lead-up to UFC 112, there was talk that ‘The Spider’ would move down to 170lbs and challenge ‘Rush’ for the welterweight title. However, UFC President Dana White was upset with Silva’s performance against Demian Maia and nixed those plans. It was unfortunate for fans who wanted to see two all time greats find out who the best was.
