The first player representing Serbia to win a Grand Slam singles title, Djokovic is also the youngest player to edge into the semifinals of all four Grand Slams in the open era at the age of 24.

Although his level of performance dropped a little bit at the end of this season, Djokovic still proved his dominance with a 70-6 record.

Legendary tennis player Pete Sampras described his season as "the best I have seen in my lifetime".
