Novak Djokovic has described Australian Open junior champion Oliver Anderson's alleged involvement in match-fixing as "very disappointing."

The world No 2 said he was saddened by reports linking Anderson to alleged match-fixing at Traralgon in October.

"Very disappointed. Very disappointing to hear, that, especially considering the fact that he's young and won the junior grand slam," Djokovic said after reaching the Qatar ExxonMobil Open.

"Obviously the quality is there and the potential is there.

"I don't understand why he has (allegedly) done it. Again, everybody has their own reasons.
They behave the way they think is best for them at the certain moment.

"Everybody makes mistakes. I hope he's going to learn from that."

The Brisbane teenager was Thursday charged by Victorian police with engaging in conduct that corrupted a betting outcome.

The news comes 12 months after the tennis world was shocked by allegations of match-fixing at the top level of the game, including suspicions that 16 top-50 players had thrown matches over the previous decade.
