The Serb is aiming at equaling Ilie Nastase`s and Ivan Lendl`s record of three consecutive titles, having won in the last two editions of the tournament as well as in 2008. Nole is currently on a 13 matches winning streak at the ATP Finals and, should he win the trophy, he would beat the record for most consecutive wins, 14, shared by Ivan Lendl and Roger Federer.
Djokovic is also on a 30 matches winning streak indoors, his last loss coming at the hands of Sam Querrey at the Paris Masters 1000, back in 2012.
