Georges St Pierre was a pay-per-view star during the height of his career from 2008 to 2013. However, Conor McGregor proudly holds that title now.
The Irishman is the current UFC flagship star and he can easily pull in impressive figures in pay-per-view, especially with the Floyd Mayweather fight increasing his popularity.
Fans have been speculating a fight between both MMA fighters as GSP returns to the Octagon. If GSP successfully proves his mettle against Michael Bisping at UFC 217, then the clamour for the fight against McGregor would surely push up.
Former UFC Featherweight champ and reigning UFC Lightweight champ McGregor would face Tony Ferguson next as he defends the title. The fight should happen late this year or early next year. If McGregor sees of his challenger and GSP his, the pair would have to consider a super fight for the sake of the fans.
