Bosnia's Musa selected the best player under the age of 21

The list was created based on the players' performance during this year's FIBA World Cup qualifiers and Musa ranked number one amongst 21 players aged under 21.

“The leader of Bosnia and Herzegovina is the country's next superstar. Dzanan Musa, who turned 19 in May, averaged 21.0 points – included 26 points against Russia – 3.0 rebounds and 2.0 steals in the February window,” FIBA said.
