Novak Djokovic, who won a record-equalling 22nd Grand Slam title on Sunday, is driven on through controversy by his determination to be the greatest ever.

An emotional Novak Djokovic beat Stefanos Tsitsipas Sunday to claim a 10th Australian Open title and equal Rafael Nadal's 22 Grand Slam crowns, a victory that returned him to world number one.

Novak Djokovic's father was absent from his son's player's box for the Australian Open final Sunday following a controversy over images of him posing with a Russian flag featuring Vladimir Putin.

Novak Djokovic has won all nine of his previous Australian Open finals so confidence is sky-high as he bids to equal Rafael Nadal's Grand Slam record and return to world number one.
