We might have got the biggest clue so far from UFC legend Georges-St Pierre that he could be heading for a return to the Octagon for doing what he does the best.

GSP, as the mixed martial arts (MMA) fighter is fondly known, fought last in the main event of UFC 167 on 16, November, 2013 at the MGM Grand Garden Arena in Las Vegas, and successfully defended his UFC welterweight title against Johny Hendricks via a split decision.

However, just a month later, the 34-year-old Canadian fighter announced his indefinite break from MMA owing to personal and professional reasons. Everyone waited for his return, but it wasn't happening.

Even UFC president Dana White spoke some weeks ago that the veteran pound-for-pound MMA fighter may have fought his last.

However, there could be a ray of hope in sight for the MMA fans over the world, who still await a final call from the veteran fighter about his future. "I'm starting to get the feeling, more and more, to come back," St-Pierre was quoted by MMA Fighting, as saying to Réseau des sports. "I watch the fights to see what's going on in my division, and I'm staying in shape. It's like a knife that I have to keep sharp just in case I ever decide to jump back in the mix. It's not for sure that it won't happen in 2015, but I'm not sure yet," he added.

St-Pierre announced in March last year that he had torn his ACL (anterior cruciate ligament) while training. But following surgery, he was medically cleared to resume training in October last year.

"I'm training hard," St-Pierre continued, as he mentions his training in his home gym in Montreal. "As you can see, I have some bumps and bruises. I didn't get these from falling down stairs."

St. Pierre has remained the UFC welterweight champion of the world, on two occasions, and was also the interim UFC welterweight champion in 2007. He defeated Matt Serra in the main event of UFC 83 on 19 April, 2008, to become the undisputed UFC welterweight champion following a second round TKO (technical knockout) win.

Since then, the Canadian superstar defeated the likes of BJ Penn, Carlos Condit and Nick Diaz, and successfully earned his record ninth title defense by getting past Hendricks in 2013.

GSP played the coach for Rory MacDonald ahead of his welterweight bout against Robbie Lawler at UFC 189 in July this year.

Lawler remains the defending UFC welterweight champion at the moment.
