Georges St-Pierre's return to mixed martial arts competition has been punctuated with a question mark once again.

In his exclusive interview with Inside MMA, the former UFC welterweight champion weighed in on the fate of his MMA career, which is currently in a standstill after his decision to take an indefinite leave of absence in December 2013.

"I needed this," he said. "To be happy, I needed it. I lost the motivation. The feeling that I want is the need to compete again. If you have a bad day [in MMA] you can get hurt really bad."

The last four fights have been the most damaging ones for Geogres St-Pierre. His last fight was against the current welterweight champion Johny Hendricks at UFC 167 in December 2013.

Lack of motivation is what "GSP" believes to be the main reason for his decision to open-endedly walk away from the sport that he dominated for almost a decade, and a weight class he was a champion at for seven straight years.

"I've been doing this for a long time, since I was 19," St-Pierre answered. "I'm 33 now. When I fought (Carlos) Condit, I was very hungry. I was very happy to be there. I wanted to do it a lot. (Nick) Diaz, a little bit less.

"And the last training camp I had with (Johny) Hendricks, I didn't have the same motivation. It went down, and I need to get back to that feeling of hunger," he added.

While Georges St-Pierre's return to MMA has remained uncertain, his trainer Firas Zahabi believes that "GSP" can still make a comeback.

"He was just about to start sparring again before he got injured," Zahabi told MMA Fighting. "I think there's a lot of martial arts left in him."

But in his most recent interview, Georges St-Pierre's return is highly dependent on his ability find the motivation that he feels he has lost.

"I truly believe if I find the fun of doing it again, and I find the fire back, I believe I'm the best in the world and if I ever come back, it's going to be to show it," St-Pierre added. "Right now, I'm enjoying my time."
