While critics are claiming it could be the end of 'The Man', Anthony Mundine said his boxing career may in fact benefit after his shock loss to Garth Wood on Wednesday night.The experienced Mundine was heavily backed to outclass Wood, but The Contender television series winner pulled off a memorable upset to score a fifth-round knockout.While Mundine admits his plans to fight in the United States will now need to be reassessed, the 35-year-old believes his shock loss may reveal a silver lining.In a roundabout way, losing can often open the door for bigger opponents in boxing, because adversaries aren't as apprehensive about taking on a struggling opponent."It's kind of bizarre in a way, I lost and I'm probably in a better situation than if I won," Mundine told Fox Sports on Thursday."In sport I've already achieved greatness in what I've achieved in my career both in boxing and in league, but even more greatness comes from adversity so it could be a blessing in disguise."Maybe I didn't have the hunger or the desire like I did when I came into the sport. I was so hungry I was like a Wood, I would do anything to win."Not just with last night's fight, but maybe the last half a dozen fights, the eye of the tiger's not there and maybe this will help me get it back."Mundine's self-confidence has earned him more critics than almost anyone in Australian sport, and many take glee when he suffers a fall.But the former St George Dragons and Brisbane Broncos NRL star invited his doomsayers to "have their fun" and indicated that retirement is not an option as he chases a junior middleweight world title."They can sing their tune now and people, the doubters and the non-believers can have their fun. But I came back before and I know The Man can come back again, I know that," he said."I still have the desire to do what no man's done and that's go down to the junior middleweight and win the title, but I'm going to talk to my team, we've got so many options."Knowing me and my competitiveness, I wouldn't mind a rematch (with Wood), but it's up to the team. The first goal is stepping in and getting the junior middleweight title and become the first man ever to do it."
