After seeing his debut world title bout end in controversy on Saturday against Hassan N'Dam, London Olympic gold medalist Ryota Murata believes there is some unfinished business in his career.

"After London I felt I've done enough after winning the gold, but I'm not feeling like that this time," Murata, who lost a split decision to the Frenchman in the WBA middleweight fight, said Monday.

Two judges scored 115-112 and 116-111 in favor of N'Dam at Ariake Coliseum, while the last had Murata at 117-110 in a bout in which N'Dam was floored in the fourth round.

WBA President Gilberto Jesus Mendoza took to Twitter on Sunday to reveal he also had Murata as the winner by 117-110, and stated he will demand a rematch between the pair.

Teiken Promotion president Akihiko Honda, who was enraged after the bout blasting the decision as one that "discredits boxing," said there has been no contact made yet by the organization but claimed there are other potential suitors.

"We've had talks (of a rematch) from the WBC and the WBO, too," Honda said. "We'll make the best choice we can if Murata says he wants one. A WBA rematch is also an option."

Murata, who was bidding to become the second middleweight champion from Japan after a 22-year wait, was coy over his future after the bout but definitely saw positives out of it.

"I wasn't behind in a bout at the world level. That gave me confidence," Murata, now 12-1 in his career with nine knockout wins, said. "I'll have a good rest and decide (about the future)."
