GSP said he‘ll never fight again after age 40, he thinks he has no business fighting after that age. GSP is 38. Tony will fight Khabib in April and likely lose. Khabib fights twice a year at best. GSP vs. Khabib in November or December of 2020. 39 year old GSP no one can call done. Khabib wins and he’s the greatest MMA artist ever. I have Khabib by decision.
