Former UFC welterweight champion Georges St-Pierre hasn’t even had his comeback fight yet (although he does have an opponent), but he already has his sights set on his eventual retirement fight.

According to St-Pierre’s longtime boxing coach Freddie Roach, the GSP camp is tentatively eyeing up Conor McGregor as a potential finale for the Canadian MMA legend.

“With the last fight, we’re hoping for it to be Conor McGregor,” Roach told Fight Hub TV. “Who wouldn’t want that fight? I mean it’s a big fight.”

“We’d have to maybe cut weight, meet in the middle somewhere, but there’s long negotiations that could still happen, of course. But who wouldn’t want that fight?”

St-Pierre has fought exclusively at 170 pounds during his UFC career so far, but will debut at middleweight when he fights Michael Bisping for the title later this year. McGregor has only fought at 170 twice, during his memorable pair of bouts with Stockton bad boy Nate Diaz. McGregor has been the featherweight champion (145 pounds) and remains the lightweight champion (155 pounds).

GSP will turn 36 soon, and is believed to be on a four-fight contract with the UFC after renegotiating terms before his return. If he does wait until the fourth and final fight to square off with McGregor, he could very well be 38-years by the time it happens.

Roach also responded to the criticism that St-Pierre has received for getting an immediate title shot despite being away from the sport for almost four years.

“That was the fight that was offered to us, through Dana [White],” he added. “[He asked us] ‘do you want him [Bisping]?’ And we all thought about it, and we all said yes.”
