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.
