News broke yesterday on social media that legendary MMA fighter Georges St-Pierre was set to draw the curtains on an iconic career that has spanned over 17 years.

The two-weight UFC champion is arguably one of the biggest names and pay-per-view draws in the business, but after last competing in late 2017, GSP sees no future in the sport that created his legacy anymore.

Last year St-Pierre indicated that he was only interested in making big-name, big-money fights with the little time left he had of his career, targeting the winner of the UFC 229 clash between Khabib Nurmagomedov and Conor McGregor.

We all know how that one ended up and the repercussions that came with the events, but even before that fight happened, Dana White shot down any chances of GSP stepping in the Octagon with either of them.

After dumping the Middleweight Championship that he claimed off Michael Bisping due to injury, the UFC President wanted to see GSP return at welterweight and not cut down to the 155 division which may have explained further his lack of desire to facilitate a huge payday.

The currently suspended Khabib seemingly won't take no for an answer though from both GSP and White, and has taken to his official Instagram account to lay down the gauntlet to the Canadian.

Tagging St-Pierre in his post, Khabib stated: "Let’s do it in November.

"After this fight you can retire. I grow up on your fights, and have nothing but respect for you, and I believe showed that to you George when you were in Moscow.

"But, it would be honor for me to share Octagon with one of the greatest fighters of all time.

"Let’s do it 155 lbs, or I give away 5lbs to you, cause you never done 155. Well, it’s your choice 155 or 160.

"Montreal, NYC, Moscow or Abu Dhabi. Send me location my Friend. 📍"

It would be huge if St-Pierre's career went out against arguably the best all-round competitor in the UFC currently, but it seems to be too little, too late.

White seems to have already made up his mind and with a press conference set in Montreal for what appears to be GSP's retirement speech, MMA fans are going to be left wondering 'What if?' for a very long time.
