'Monster' Xu certain best has yet to come

China's only reigning professional world boxing champion, Xu Can, believes his journey in the ring has only just begun.

Xu, known as "the Monster", successfully defended his WBA featherweight title for the second time with a unanimous decision against American Manny Robles III last month in California.

The 25-year-old threw an astounding 1,562 punches in the fight－a new featherweight record and the sixth-highest total in all divisions, according to CompuBox stats. His blitz was even more impressive given he didn't seem to tire as the fight went on, throwing (125) and landing (46) the most punches in the 12th and final round.
