Add former UFC welterweight champion Georges St-Pierre and the Mixed Martial Arts Athletes Association to the list of fighters in Conor McGregor's crosshairs

St-Pierre, along former UFC champions Cain Velasquez and TJ Dillashaw as well as fighters Tim Kennedy, Donald Cerrone and former Bellator MMA promoter Bjorn Rebney, announced their roles in the MMAAA in a press conference last November

The main goal of the association is the implementation of a collective bargaining agreement that includes a 50 percent share of UFC revenue and a settlement payout for current and past fighters.

In the past, St-Pierre revealed it would take a fighter of McGregor's status to really get the movement off the ground, claiming the Irishman could make even more money with the MMAAA.

But speaking in front of a crowd of 5,000 fans, McGregor revealed the much talked about press conference, along with St-Pierre's comments, surrounding the MMAAA puzzled him more than anything else.

"I'm watching this union thing, it like a press conference, and I'm like, what the f-ck is going on here?" McGregor said during an hour-long interview in Manchester. "They're standing up, they're all wearing the same t-shirt. They're saying, 'Conor, please. Conor, please, you know what's right. Help us out, Conor.' And Georges is saying, 'Conor's a good person. I know he gets paid well, but he doesn't get paid enough.' And I'm like, what the f*ck are you talking about?"

In terms of competition, St-Pierre (25-2) has not competed since defending his 170-pound title against Johny Hendricks at UFC 167 in November 2013. Immediately after his win, he announced he would be taking an indefinite hiatus from competition.But after three years away from the sport, the French Canadian revealed he was looking to return to the Octagon. Specifically targeting the upcoming UFC 206 in Toronto, the St-Pierre made it known his team was working with the UFC on a new deal. But these talks fell apart when the UFC was sold to WME-IMG in July, according to St-Pierre.

McGregor was quick to call out St-Pierre on his past negotiations with the UFC along for his role in the association.

"The only reason you're standing in the middle of that union is because you (St-Pierre) couldn't get the deal you want," said McGregor. "You're the fakest of everyone up there."

St-Pierre has yet to respond to McGregor's comments.
